# 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.

#### Add data to Collection metafield

1. Open the collection you’d like to add a tag filtering too
2. Scroll to the bottom **Metafields** area

   * There's no need to include "All" as that will be the first link within tag filtering
   * 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>
4. Click **Save**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.brickspacelab.com/paper/guides/collections/adding-nested-menu.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
