For example, drop-down menus. In Metro 4 you can transform any element to <code>dropdown</code>. Element must have <code>display: block</code> css property. To create <code>dropdown</code> element you can add role <code>data-role="dropdown"</code> and define <code>toggle</code> for it with attribute <code>data-toggle-element="..."</code>. At the same time, only one dropdown element can be opened. </p> <div class="example"> <button class="button" id="dropdown_toggle_1">Drop block</button> <div class="pos-relative"> <div class="bg-red fg-white" data-role="dropdown" data-toggle-element="#dropdown_toggle_1"> <p class="p-10 text-center">In Metro 4 you can transform any element to dropdown.</p> </div> </div> </div> <pre><code class="html"> <button class="button" id="dropdown_toggle_1">Drop block</button> <div class="pos-relative"> <div class="bg-red fg-white" data-role="dropdown" data-toggle-element="#dropdown_toggle_1"> <p class="p-10 text-center"> In Metro 4 you can transform any element to dropdown. </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>effect</td> <td><code>data-effect</code></td> <td>slide</td> <td>Show/Close effect.
