Collapse

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

How it works

The collapse JavaScript plugin is used to show and hide content. Buttons or anchors are used as triggers that are mapped to specific elements you toggle. Collapsing an element will animate the height from it's current value to 0. Given how CSS handles animations, you cannot use padding on a .collapse element. Instead, use the class as an independent wrapping element.

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

You can use a link with the href attribute, or a button with the data-bs-target attribute. In both cases, the data-bs-toggle="collapse" is required.
