This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should have a value of <code>aria-expanded="false"</code>. If you've set the collapsible element to be open by default using the <code>in</code> class, set <code>aria-expanded="true"</code> on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.</p><p>Additionally, if your control element is targetting a single collapsible element – i.e. the <code>data-target</code> attribute is pointing to an <code>id</code> selector – you may add an additional <code>aria-controls</code> attribute to the control element, containing the <code>id</code> of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.</p></div><h2id=collapse-usage>Usage</h2><p>The collapse plugin utilizes a few classes to handle the heavy lifting:</p><ul><li><code>.collapse</code> hides the content</li><li><code>.collapse.in</code> shows the content</li><li><code>.collapsing</code> is added when the transition starts, and removed when it finishes</li></ul><p>These classes can be found in <code>component-animations.less</code>.</p><h3>Via data attributes</h3><p>Just add <code>data-toggle="collapse"</code> and a <code>data-target</code> to the element to automatically assign control of a collapsible element. The <code>data-target</code> attribute accepts a CSS selector to apply the collapse to. Be sure to add the class <code>collapse</code> to the collapsible element.

The subnavigation on the right is a live demo of the affix plugin.</p><hrclass=bs-docs-separator><h2id=affix-usage>Usage</h2><p>Use the affix plugin via data attributes or manually with your own JavaScript. <strongclass=text-danger>In both situations, you must provide CSS for the positioning and width of your affixed content.</strong></p><p>Note: Do not use the affix plugin on an element contained in a relatively positioned element, such as a pulled or pushed column, due to a <ahref=https://github.com/twbs/bootstrap/issues/12126>Safari rendering bug</a>.</p><h3>Positioning via CSS</h3><p>The affix plugin toggles between three classes, each representing a particular state: <code>.affix</code>, <code>.affix-top</code>, and <code>.affix-bottom</code>. You must provide the styles, with the exception of <code>position: fixed;</code> on <code>.affix</code>, for these classes yourself (independent of this plugin) to handle the actual positions.</p><p>Here's how the affix plugin works:</p><ol><li>To start, the plugin adds <code>.affix-top</code> to indicate the element is in its top-most position. At this point no CSS positioning is required.</li><li>Scrolling past the element you want affixed should trigger the actual affixing. This is where <code>.affix</code> replaces <code>.affix-top</code> and sets <code>position: fixed;</code> (provided by Bootstrap's CSS).</li><li>If a bottom offset is defined, scrolling past it should replace <code>.affix</code> with <code>.affix-bottom</code>. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add <code>position: absolute;</code> when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the element from there.</li></ol><p>Follow the above steps to set your CSS for either of the usage options below.</p><h3>Via data attributes</h3><p>To easily add affix behavior to any element, just add <code>data-spy="affix"</code> to the element you want to spy on. Use offsets to define when to toggle the pinning of an element.</p><figureclass=highlight><pre><codeclass=language-htmldata-lang=html><spanclass=nt><div</span><spanclass=na>data-spy=</span><spanclass=s>"affix"</span><spanclass=na>data-offset-top=</span><spanclass=s>"60"</span><spanclass=na>data-offset-bottom=</span><spanclass=s>"200"</span><spanclass=nt>></span>
