# Add a nested menu

Each collection can be set up with nested navigation. This is useful if you have a large collection with multiple sub-groupings within. For example, you may have a collection titled Accessories using nested navigation you could then set up links to Wallets, Phone Cases, and Bags.

In this example clicking "Elastic" would navigate to a new page loading the "Elastic" collection page.

   * Each entry should match a tag that is present within your collection
   * This text must be formatted in a specific way. Please ensure each menu item is separated by “&” then ensure each title and url for each item is separated by a “,”.
   * It should look something like this:
     * <pre><code><strong>Tops,/collections/tops&#x26;Bags,/collections/bags&#x26;Shorts,/collections/short
       </strong></code></pre>
