Component-wrapper for collapse animation with css for elements with variable and dynamic height

react-css-collapse

Collapse component with css transition for elements with variable and dynamic height.

⚠️ ️You need to specify the transition property or add a class selector with style (transition) in your own stylesheet to add animation. You can copy the smashing example below 💅

.react-css-collapse-transition {
  transition: height 250ms cubic-bezier(.4, 0, .2, 1);
}

Installation

npm install --save react-css-collapse

import Collapse from 'react-css-collapse';

<Collapse isOpen={true || false}>
  <div>Random content</div>
</Collapse>

Properties

isOpen: PropTypes.boolean.isRequired

Expands or collapses content.

children: PropTypes.node.isRequired

One or multiple children with static, variable or dynamic height.

<Collapse isOpen={true}>
  <p>Paragraph of text</p>
  <p>Another paragraph is also OK</p>
  <p>Images and any other content are ok too</p>
  <img src="cutecat.gif" />
</Collapse>

className: PropType.string

You can specify a className with your desired style and animation. By default react-css-collapse-transition will be added to the component.

transition: PropType.string

You can also specify a transition in line by using the transition prop.

<Collapse transition="height 250ms cubic-bezier(.4, 0, .2, 1)">
  <p>Paragraph of text</p>
</Collapse>

onRest: PropTypes.func

Callback function for when your transition on height (specified in className) is finished. It can be used to trigger any function after transition is done.

ARIA and data attributes

Collapse transfers aria- and data- attributes to the component's rendered DOM element. For example this can be used to set the aria-hidden attribute:

<Collapse isOpen={isOpenState} aria-hidden={isOpenState ? 'false' : 'true'}>
  <p>Paragraph of text</p>
</Collapse>
