Vue Bootstrap Collapse

Vue Collapse - Bootstrap 4 & Material Design

Vue Bootstrap collapse is a component which toggles content. Useful for grouping great amount of texts and/or graphics into expanding and collapsing items.


How it works

Collapse 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:

You can use a link with the href attribute, or a button.

Multiple targets

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