Angular Collapse Component

Angular Collapse directive toggles the visibility of content across your project with a few classes and some scripts. Useful for a large amount of content.

How it works

The collapse component 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 its 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.

Examples

You can use it with a link or a button element.

Link

Horizontal

Add the horizontal property to transition the width instead of height and set a width on the immediate child element.

Multiple targets

A c-button can show and hide multiple elements.
