<h2 id="how-it-works">How it works</h2>
|
||
|
||
<p>Scrollspy has a few requirements to function properly:</p>
|
||
|
||
<ul>
|
||
<li>If you’re building our JavaScript from source, it <a href="/docs/4.0/getting-started/javascript/#util">requires <code class="highlighter-rouge">util.js</code></a>.</li>
|
||
<li>It must be used on a Bootstrap <a href="/docs/4.0/components/navs/">nav component</a> or <a href="/docs/4.0/components/list-group/">list group</a>.</li>
|
||
<li>Scrollspy requires <code class="highlighter-rouge">position: relative;</code> on the element you’re spying on, usually the <code class="highlighter-rouge"><body></code>.</li>
|
||
<li>When spying on elements other than the <code class="highlighter-rouge"><body></code>, be sure to have a <code class="highlighter-rouge">height</code> set and <code class="highlighter-rouge">overflow-y: scroll;</code> applied.</li>
|
||
<li>Anchors (<code class="highlighter-rouge"><a></code>) are required and must point to an element with that <code class="highlighter-rouge">id</code>.</li>
|
||
</ul>
|
||
|
||
<p>When successfully implemented, your nav or list group will update accordingly, moving the <code class="highlighter-rouge">.active</code> class from one item to the next based on their associated targets.</p>
|
||
|
||
<h2 id="example-in-navbar">Example in navbar</h2>
|
||
|
||
<p>Scroll the area below the navbar and watch the active class change. The dropdown items will be highlighted as well.</p>

<p>To easily add scrollspy behavior to your topbar navigation, add <code class="highlighter-rouge">data-spy="scroll"</code> to the element you want to spy on (most typically this would be the <code class="highlighter-rouge"><body></code>). Then add the <code class="highlighter-rouge">data-target</code> attribute with the ID or class of the parent element of any Bootstrap <code class="highlighter-rouge">.nav</code> component.</p>
