Dropdowns

Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.

Single button

Any single .btn can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either <button> elements:

<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown button
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
</ul>
</div>

And with <a> elements:

<div class="dropdown">
<a class="btn btn-secondary dropdown-toggle" href="#" role="button" id="dropdownMenuLink" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown link
</a>
<ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
</ul>
</div>

The best part is you can do this with any button variant, too:

<div class="btn-group">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
    Action
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

Split button

Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of .dropdown-toggle-split for proper spacing around the dropdown caret.

We use this extra class to reduce the horizontal padding on either side of the caret by 25% and remove the margin-left that’s added for regular button dropdowns. Those extra changes keep the caret centered in the split button and provide a more appropriately sized hit area next to the main button.

<div class="btn-group">
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-primary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
    <span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

Sizing

Button dropdowns work with buttons of all sizes, including default and split dropdown buttons.

<div class="btn-group">
<button class="btn btn-secondary btn-lg dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">
    Large button
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>
<div class="btn-group">
<button class="btn btn-secondary btn-lg" type="button">Large split button</button>
<button type="button" class="btn btn-primary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
    <span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

<div class="btn-group">
<button class="btn btn-secondary btn-lg dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">
    Small button
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>
<div class="btn-group">
<button class="btn btn-secondary btn-lg" type="button">Small split button</button>
<button type="button" class="btn btn-primary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
    <span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

Dark dropdowns

Opt into darker dropdowns to match a dark navbar or custom style by adding .dropdown-menu-dark onto an existing .dropdown-menu. No changes are required to the dropdown items.

<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton2" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown Button
</button>
<ul class="dropdown-menu dropdown-menu-dark" aria-labelledby="dropdownMenuButton2">
    <li><a class="dropdown-item active" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

And putting it to use in a navbar:

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
<div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavDarkDropdown" aria-controls="navbarNavDarkDropdown" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavDarkDropdown">
        <ul class="navbar-nav">
            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="navbarDarkDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false">
                    Dropdown
                </a>
                <ul class="dropdown-menu dropdown-menu-dark" aria-labelledby="navbarDarkDropdownMenuLink">
                    <li><a class="dropdown-item" href="#">Action</a></li>
                    <li><a class="dropdown-item" href="#">Another action</a></li>
                    <li><a class="dropdown-item" href="#">Something else here</a></li>
                </ul>
            </li>
        </ul>    
    </div>
</div>
</nav>

Dropup

Trigger dropdown menus above elements by adding .dropup to the parent element.

<div class="btn-group dropup">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
    Dropup
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item active" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>
<div class="btn-group dropup">
<button type="button" class="btn btn-secondary"> Split dropup</button>
<button type="button" class="btn btn-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
    <span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

Dropright

Trigger dropdown menus at the right of the elements by adding .dropend to the parent element.

<div class="btn-group dropend">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
    Dropright
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item active" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>
<div class="btn-group dropend">
<button type="button" class="btn btn-secondary"> Split dropend</button>
<button type="button" class="btn btn-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
    <span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

Dropleft

Trigger dropdown menus at the left of the elements by adding .dropstart to the parent element.

<div class="btn-group dropstart">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
    Dropstart
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item active" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>
<div class="btn-group">
<div class="btn-group dropstart">
    <button type="button" class="btn btn-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
        <span class="visually-hidden">Toggle Dropdown</span>
    </button>
    <ul class="dropdown-menu">
        <li><a class="dropdown-item" href="#">Action</a></li>
        <li><a class="dropdown-item" href="#">Another action</a></li>
        <li><a class="dropdown-item" href="#">Something else here</a></li>
        <li><hr class="dropdown-divider"></li>
        <li><a class="dropdown-item" href="#">Separated link</a></li>
    </ul>
</div>
<button type="button" class="btn btn-secondary"> 
    Split dropstart
</button>
</div>

Menu items

You can use <a> or <button> elements as dropdown items.

<div class="dropdown">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu2">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li><button class="dropdown-item" type="button">Another action</button></li>
    <li><button class="dropdown-item" type="button">Something else here</button></li>
</ul>
</div>

Active

Add .active to items in the dropdown to style them as active. To convey the active state to assistive technologies, use the aria-current attribute — using the page value for the current page, or true for the current item in a set.

<ul class="dropdown-menu">
<li><a class="dropdown-item" href="#">Regular link</a></li>
<li><a class="dropdown-item active" href="#" aria-current="true">Active link</a></li>
<li><a class="dropdown-item" href="#">Another link</a></li>
</ul>

Disabled

Add .disabled to items in the dropdown to style them as disabled.

<ul class="dropdown-menu">
<li><a class="dropdown-item" href="#">Regular link</a></li>
<li><a class="dropdown-item disabled" href="#" tabindex="-1" aria-disabled="true">Disabled link</a></li>
<li><a class="dropdown-item" href="#">Another link</a></li>
</ul>

Menu alignment

By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. You can change this with the directional .drop* classes, but you can also control them with additional modifier classes.

Add .dropdown-menu-end to a .dropdown-menu to right align the dropdown menu. Directions are mirrored when using Bootstrap in RTL, meaning .dropdown-menu-end will appear on the left side.

<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
    Right-aligned menu example
</button>
<ul class="dropdown-menu dropdown-menu-end">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li><button class="dropdown-item" type="button">Another action</button></li>
    <li><button class="dropdown-item" type="button">Something else here</button></li>
</ul>
</div>

Responsive alignment

If you want to use responsive alignment, disable dynamic positioning by adding the data-bs-display="static" attribute and use the responsive variation classes.

To align right the dropdown menu with the given breakpoint or larger, add .dropdown-menu{-sm|-md|-lg|-xl|-xxl}-end.

<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" data-bs-display="static" aria-expanded="false">
        Left-aligned but right aligned when large screen
</button>
<ul class="dropdown-menu dropdown-menu-lg-end">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li><button class="dropdown-item" type="button">Another action</button></li>
    <li><button class="dropdown-item" type="button">Something else here</button></li>
</ul>
</div>

To align left the dropdown menu with the given breakpoint or larger, add .dropdown-menu-end and .dropdown-menu{-sm|-md|-lg|-xl|-xxl}-start.

<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" data-bs-display="static" aria-expanded="false">
    Right-aligned but left aligned when large screen
</button>
<ul class="dropdown-menu dropdown-menu-end dropdown-menu-lg-start">
    <li><button class="dropdown-item" type="button">Action</button></li>
    <li><button class="dropdown-item" type="button">Another action</button></li>
    <li><button class="dropdown-item" type="button">Something else here</button></li>
</ul>
</div>

Alignment options

Taking most of the options shown above, here’s a small kitchen sink demo of various dropdown alignment options in one place.

<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" data-bs-display="static" aria-expanded="false">
    Right-aligned, left-aligned lg
</button>
<ul class="dropdown-menu dropdown-menu-end dropdown-menu-lg-start">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>

Menu content

Headers

Add a header to label sections of actions in any dropdown menu.

<ul class="dropdown-menu">
<li><h6 class="dropdown-header">Dropdown header</h6></li>
<li><a class="dropdown-item" href="#">Action</a></li>
<li><a class="dropdown-item" href="#">Another action</a></li>
</ul>

Dividers

Separate groups of related menu items with a divider.

<ul class="dropdown-menu">
<li><a class="dropdown-item" href="#">Action</a></li>
<li><a class="dropdown-item" href="#">Another action</a></li>
<li><a class="dropdown-item" href="#">Something else here</a></li>
<li><hr class="dropdown-divider"></li>
<li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>

Text

Place any freeform text within a dropdown menu with text and use spacing utilities. Note that you’ll likely need additional sizing styles to constrain the menu width.

<div class="dropdown-menu p-4 text-muted" style="max-width: 200px;">
<p>
    Some example text that's free-flowing within the dropdown menu.
<p>
<p>
    And this is more example text.
</p>
</div>

Forms

Put a form within a dropdown menu, or make it into a dropdown menu, and use margin or padding utilities to give it the negative space you require.

<div class="dropdown-menu">
<form class="px-4 py-3">
    <div class="mb-3">
        <label for="exampleDropdownFormEmail1" class="form-label">Email address</label>
        <input type="email" class="form-control" id="exampleDropdownFormEmail1" placeholder="email@example.com">
    </div>   
    <div class="mb-3">
        <label for="exampleDropdownFormPassword1" class="form-label">Password</label>
        <input type="password" class="form-control" id="exampleDropdownFormPassword1" placeholder="Password">
    </div> 
    <div class="mb-3">
        <div class="mb-3">
            <input type="checkbox" class="form-check-input" id="dropdownCheck">
            <label class="form-check-label" for="dropdownCheck">Remember me</label>
        </div> 
    </div> 
    <button type="submit" class="btn btn-primary"> Sign in </button>
</form>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">New around here? Sign up</a>
<a class="dropdown-item" href="#">Forgot password?</a>
</div>

<div class="dropdown-menu">
<form class="px-4 py-3">
    <div class="mb-3">
        <label for="exampleDropdownFormEmail2" class="form-label">Email address</label>
        <input type="email" class="form-control" id="exampleDropdownFormEmail2" placeholder="email@example.com">
    </div>   
    <div class="mb-3">
        <label for="exampleDropdownFormPassword2" class="form-label">Password</label>
        <input type="password" class="form-control" id="exampleDropdownFormPassword2" placeholder="Password">
    </div> 
    <div class="mb-3">
        <div class="form-check">
            <input type="checkbox" class="form-check-input" id="dropdownCheck2">
            <label class="form-check-label" for="dropdownCheck2">Remember me</label>
        </div> 
    </div> 
    <button type="submit" class="btn btn-primary"> Sign in </button>
</form>
</div>

Dropdown options

Use data-bs-offset or data-bs-reference to change the location of the dropdown.

<div class="dropdown me-1">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" data-bs-display="static" aria-expanded="false">
    Offset
</button>
<ul class="dropdown-menu dropdown-menu-end dropdown-menu-lg-start">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
</ul>
</div>   
<div class="btn-group">
<button type="button" class="btn btn-secondary">Reference</button> 
<button type="button" class="btn btn-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
    <span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

Auto close behavior

By default, the dropdown menu is closed when clicking inside or outside the dropdown menu. You can use the autoClose option to change this behavior of the dropdown.

<div class="btn-group">
<button class="btn btn-secondary dropdown-toggle" type="button" id="defaultDropdown" data-bs-toggle="dropdown" data-bs-auto-close="true" aria-expanded="false">
    Default dropdown
</button>
<ul class="dropdown-menu aria-labelledby="defaultDropdown">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>
<div class="btn-group">
<button class="btn btn-secondary dropdown-toggle" type="button" id="defaultDropdown" data-bs-toggle="dropdown" data-bs-auto-close="true" aria-expanded="false">
    Clickable outside
</button>
<ul class="dropdown-menu aria-labelledby="dropdownMenuClickableOutside">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>
<div class="btn-group">
<button class="btn btn-secondary dropdown-toggle" type="button" id="defaultDropdown" data-bs-toggle="dropdown" data-bs-auto-close="true" aria-expanded="false">
    Clickable inside
</button>
<ul class="dropdown-menu aria-labelledby="dropdownMenuClickableInside">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>
<div class="btn-group">
<button class="btn btn-secondary dropdown-toggle" type="button" id="defaultDropdown" data-bs-toggle="dropdown" data-bs-auto-close="true" aria-expanded="false">
    Manual close
</button>
<ul class="dropdown-menu aria-labelledby="dropdownMenuClickable">
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
    <li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>
