React Collapse Component

Collapse

React collapse component toggles the visibility of content across your project with a few classes and some scripts. Useful for a large amount of content.

Other frameworks

CoreUI components are available as native Angular, Bootstrap (Vanilla JS), and Vue components. To learn more please visit the following pages.

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.

Example#

You can use a link or a button component.

Link

Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.

const [visible, setVisible] = useState(false)
return (
  <>
    <CButton
      color="primary"
      href="#"
      onClick={(event) => {
        event.preventDefault()
        setVisible(!visible)
      }}
    >
      Link
    </CButton>
    <CButton color="primary" onClick={() => setVisible(!visible)}>
      Button
    </CButton>
    <CCollapse visible={visible}>
      <CCard className="mt-3">
        <CCardBody>
          Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad
          squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt
          sapiente ea proident.
        </CCardBody>
      </CCard>
    </CCollapse>
  </>
)

Horizontal#

The collapse plugin also supports horizontal collapsing. Add the horizontal property to transition the width instead of height and set a width on the immediate child element.

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

const [visible, setVisible] = useState(false)
return (
  <>
    <CButton
      className="mb-3"
      onClick={() => setVisible(!visible)}
      aria-expanded={visible}
      aria-controls="collapseWidthExample"
    >
      Button
    </CButton>
    <div style={{ minHeight: '120px' }}>
      <CCollapse id="collapseWidthExample" horizontal visible={visible}>
        <CCard style={{ width: '300px' }}>
          <CCardBody>
            This is some placeholder content for a horizontal collapse. It's hidden by default and
            shown when triggered.
          </CCardBody>
        </CCard>
      </CCollapse>
    </div>
  </>
)

Multiple targets#

A <CButton> can show and hide multiple elements.

const [visibleA, setVisibleA] = useState(false)
