For example, any collapsible panels. In Metro 4 you can transform any element to <code>collapsible</code>. Element must have <code>display: block</code> css property. To create <code>collapse</code> element you can add role <code>data-role="collapse"</code> and define <code>toggle</code> for it with attribute <code>data-toggle-element="..."</code>. <strong>In contrast to the dropdown, the collapsible elements can be a lot open at the same time</strong>. </p> <div class="example"> <button class="button" id="collapse_toggle_1">Collapse block</button> <div class="pos-relative"> <div class="bg-red fg-white" data-role="collapse" data-toggle-element="#collapse_toggle_1"> <p class="p-10 text-center">In Metro 4 you can transform any element to collapsible.</p> </div> </div> </div> <pre><code class="html"> <button class="button" id="collapse_toggle_1">Collapse block</button> <div class="pos-relative"> <div class="bg-red fg-white" data-role="collapse" data-toggle-element="#collapse_toggle_1"> <p class="p-10 text-center"> In Metro 4 you can transform any element to collapsible. </p> </div> </div> </code></pre> <p> By default, the collapsible element is open. If you need to create an element with collapsing state at start, add attribute <code>data-collapsed="true"</code>. </p> <div class="example"> <button class="button" id="collapse_toggle_2">Collapse block</button> <div class="pos-relative"> <div class="bg-red fg-white" data-role="collapse" data-toggle-element="#collapse_toggle_2" data-collapsed="true"> <p class="p-10 text-center"> In Metro 4 you can transform any element to collapsible. </p> </div> </div> </div> <pre><code class="html"> <button class="button" id="collapse_toggle_2">Collapse block</button> <div class="pos-relative"> <div class="bg-red fg-white" data-role="collapse" data-toggle-element="#collapse_toggle_2" data-collapsed="true"> <p class="p-10 text-center"> In Metro 4 you can transform any element to collapsible. </p> </div> </div> </code></pre>  <h3 id="_dropdown_options">Options</h3> <p> Each dropdown element has a number of option: </p> <table class="table cell-border table-border options-table"> <thead> <tr> <th>Option</th> <th>Data-*</th> <th>Default</th> <th>Desc</th> </tr> </thead> <tbody> <tr> <td>collapsed</td> <td><code>data-collapsed</code></td> <td>false</td> <td>Initial state for element. Values: true, false</td> </tr> <tr> <td>effect</td> <td><code>data-effect</code></td> <td>slide</td> <td>Show/Close effect. Values: slide, fade</td> </tr> <tr> <td>toggleElement</td> <td><code>data-toggle-element</code></td> <td>null</td> <td>Selector who specified toggle element</td> </tr> <tr> <td>duration</td> <td><code>data-duration</code></td> <td>300</td> <td>Effect duration in milliseconds</td> </tr> <tr> <td>onExpand</td> <td><code>data-on-drop</code></td> <td>Metro.noop</td> <td>Event fired when element dropped</td> </tr> <tr> <td>onCollapse</td> <td><code>data-on-up</code></td> <td>Metro.noop</td> <td>Event fired when element close</td> </tr> <tr> <td>onCollapseCreate</td> <td><code>data-on-dropdown-create</code></td> <td>Metro.noop</td> <td>Event fired when element created</td> </tr> </tbody> </table> <h3 id="_dropdown_methods">Methods</h3> <p> Each collapse component has next methods: <code>collapse()</code>, <code>expand()</code>, <code>isCollapsed()</code>. You can use this methods to interact with component. </p> <pre><code class="javascript"> el = $('#el').data('collapse'); var collapsed = el.isCollapsed(); var f1 = collapsed === true ? "expand" : "collapse"; var f2 = collapsed === true ? "collapse" : "expand"; el[f1](); setTimeout(function(){ el[f2](); }, 2000); </code></pre> <p class="mb-4"> You can change attribute <code>data-collapsed</code> at runtime to change element state. </p> </main> </div> </div> <script src="docsearch/docsearch.min.js"></script> <script src="js/jquery-3.3.1.min.js"></script> <script src="metro/js/metro.js?ver=@@b-version"></script> <script src="highlight/highlight.pack.js"></script> <script src="js/clipboard.min.js"></script> <script src="js/site.js"></script>    </body> </html>
