Tooltips

Documentation and examples for adding custom Bootstrap tooltips with CSS and JavaScript using CSS3 for animations and data-bs-attributes for local title storage.

Overview

Things to know when using the tooltip plugin:

• Tooltips are opt-in for performance reasons, so you must initialize them yourself.
• Tooltips with zero-length titles are never displayed.
• Specify container: 'body' to avoid rendering problems in more complex components (like our input groups, button groups, etc).
• Triggering tooltips on hidden elements will not work.
• Tooltips for .disabled or disabled elements must be triggered on a wrapper element.
• When triggered from hyperlinks that span multiple lines, tooltips will be centered. Use white-space: nowrap; on your <a>s to avoid this behavior.
• Tooltips must be hidden before their corresponding elements have been removed from the DOM.
• Tooltips can be triggered thanks to an element inside a shadow DOM.

Example: Enable tooltips everywhere

One way to initialize all tooltips on a page would be to select them by their data-bs-toggle attribute:

var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
return new bootstrap.Tooltip(tooltipTriggerEl)
})

Examples

Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left. Directions are mirrored when using Bootstrap in RTL.

<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="top" title="Tooltip on top" >
    Tooltip on top
</button>
<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="right" title="Tooltip on right">
    Tooltip on right
</button>
<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="bottom" title="Tooltip on bottom">
    Tooltip on bottom
</button>
<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="left" title="Tooltip on left">
    Tooltip on left
</button>

And with custom HTML added:

<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
    Tooltip with HTML
</button>
