Collapse helps to hide or conceal a section of a form, typically by minimizing or folding it into a smaller, more compact view.

This feature is often used to organize lengthy or complex forms, making them easier to navigate and reducing visual clutter.

Use Case

  1. Improved form organization
  2. Reduced visual clutter
  3. Enhanced user experience
  4. Conditional visibility
  5. Registration forms
  6. Survey forms
  7. Order forms
  8. Contact forms
  9. Customer feedback forms


There are a number of ways to add interactivity to the Collapse component.

Some of the most common methods include:

  1. Toggle Visibility: Implement the collapse/expand functionality to switch an element's state between being visible and hidden on a user interface.
  2. Attach JavaScript Event Listeners: Attach event listeners to the toggle button or link using JavaScript. These listeners will detect clicks or other user interactions and trigger the collapse/expand functionality.
  3. Add a Toggle Button or Link: Create a toggle button or link that will trigger the collapse/expand action. This element can be placed within the header element or alongside the container element.
  4. Conditional Collapse: Show or hide specific collapse sections based on user input or form data.
  5. Nested Collapse: Organize complex forms with multiple levels of collapsible sections.
  6. Enhanced animations and transitions: Improve the visual appeal of the collapse/expand action.
  7. Accessibility considerations: Optimize the collapse component for users with disabilities.
