Get started with Bootstrap

How it works

Toggle the visibility of content across your project with a few classes and our JavaScript plugins.

Basic 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.
Horizontal

The collapse plugin also supports horizontal collapsing. Add the .collapse-horizontal modifier class to transition the width instead of height and set a width on the immediate child element. Feel free to write your own custom Sass, use inline styles, or use our width utilities.

This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered.
Multiple targets

Some placeholder content for the first collapse component of this multi-collapse example. This panel is hidden by default but revealed when the user activates the relevant trigger.
