Collapse
Toggle the visibility of content across your project with a few classes and our JavaScript plugins.
Example
Click the buttons below to show and hide another element via class changes:
.collapse
hides content.collapsing
is applied during transitions.collapse.show
shows content
Generally, we recommend using a button with the data-bs-target
attribute. While not recommended from a semantic point of view, you can also use a link with the href
attribute (and a role="button"
). In both cases, the data-bs-toggle="collapse"
is required.
Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.
This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered.

Multiple targets
A <button>
or <a>
can show and hide multiple elements by referencing them with a selector in its href
or data-bs-target
attribute.Multiple <button>
or <a>
can show and hide an element if they each reference it with their href
or data-bs-target
attribute
