--- title: Dropdown description: Dropdown panes are little happy sprites which can be revealed on click or hover. sass: scss/components/_dropdown.scss js: js/foundation.dropdown.js video: '0F68zptD_nQ' --- <div class="primary callout"> <p>You might be looking for <a href="dropdown-menu.html">dropdown menus</a>, which are a separate plugin.</p> </div> ## Basics To create a dropdown pane, add the class `.dropdown-pane` and the attribute `data-dropdown` to an element. Give the dropdown a unique ID as well. To create the dropdown trigger, add `data-toggle` to a `<button>`. The value of `data-toggle` is the ID of the dropdown. <p> <a class="" data-open-video="0:47"><img src="{{root}}assets/img/icons/watch-video-icon.svg" class="video-icon" height="30" width="30" alt=""> Watch this part in video</a> </p> <div class="docs-codepen-container"> <a class="codepen-logo-link" href="https://codepen.io/IamManchanda/pen/NjzByp?editors=1000" target="_blank"><img src="{{root}}assets/img/logos/edit-in-browser.svg" class="" height="" width="" alt="edit on codepen button"></a> </div> ```html_example <button class="button" type="button" data-toggle="example-dropdown">Toggle Dropdown</button> <div class="dropdown-pane" id="example-dropdown" data-dropdown data-auto-focus="true"> Example form in a dropdown. <form> <div class="grid-container"> <div class="grid-x grid-margin-x"> <div class="cell medium-6"> <label>Name <input type="text" placeholder="Kirk, James T."> </label> </div> <div class="cell medium-6"> <label>Rank <input type="text" placeholder="Captain"> </label> </div> </div> </div> </form> </div> <button class="button" type="button" data-toggle="example-dropdown-1">Hoverable Dropdown</button> <div class="dropdown-pane" id="example-dropdown-1" data-dropdown data-hover="true" data-hover-pane="true"> Just some junk that needs to be said. Or not. Your choice. </div> ``` --- ## Positioning By default, a dropdown anchors below the button that opened it. Add the class `.top`, `.right`, or `.bottom` to the dropdown to change this. <div class="docs-codepen-container"> <a class="codepen-logo-link" href="https://codepen.io/IamManchanda/pen/YVvjvz?editors=1000" target="_blank"><img src="{{root}}assets/img/logos/edit-in-browser.svg" class="" height="" width="" alt="edit on codepen button"></a> </div> ```html_example <button class="button" type="button" data-toggle="example-dropdown2">Top Aligned</button> <div class="dropdown-pane top" id="example-dropdown2" data-dropdown> Just some junk that needs to be said. Or not. Your choice. </div> ``` <button class="button" type="button" data-toggle="example-dropdown3" style="float: right;">Left Aligned</button> <div class="dropdown-pane left" id="example-dropdown3" data-dropdown> Just some junk that needs to be said.

Or not. Your choice. </div> Adding `.float-right` or `.float-left` to the anchor will change the direction of the dropdown as well. <button class="button float-right" type="button" data-toggle="example-dropdown5">Bottom-right Aligned</button> <div class="dropdown-pane bottom" id="example-dropdown5" data-dropdown> Just some junk that needs to be said. Or not. Your choice. </div> <button class="button float-left" type="button" data-toggle="example-dropdown6">Bottom-left Aligned</button> <div class="dropdown-pane bottom" id="example-dropdown6" data-dropdown> Just some junk that needs to be said. Or not. Your choice. </div> --- ## Explicit Positioning <div class="callout primary"> <p><strong>New in v6.4:</strong> Heads up! This explicit positioning model is a new feature in v6.4.</p> </div> Wouldn't it be great if you can define both positions at the dropdown element. Dropdown has a fully explicit positioning model through which you can use both `data-position` and `data-alignment` to define both positions of the box. These dropdowns test various positioning and alignments. Valid positions are left/right/top/bottom. Valid alignments are left/right/top/bottom/center. Left align means left sides should line up. Right align means right sides should line up. Center align means centers should line up. #### Top and Bottom positioned ```html  <button class="button" type="button" data-toggle="example-dropdown-bottom-left">Toggle Dropdown</button> <div
