                        npm i @preline/collapse

Example

Click the buttons below to show and hide another element:

Basic usage

Prefer to create your own style? Here is a completely unstylized example.

                      
                        <button type="button" class="hs-collapse-toggle" id="hs-unstyled-collapse" aria-expanded="false" aria-controls="#hs-unstyled-collapse-heading" data-hs-collapse="#hs-unstyled-collapse-heading">
                          Collapse
                        </button>
                        <div id="hs-unstyled-collapse-heading" class="hs-collapse hidden w-full overflow-hidden transition-[height] duration-300" aria-labelledby="hs-unstyled-collapse">
                          This is a collapse body. It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions.
                        </div>
