# Subcollections

Cross-promote other collections with subcollections. Display a carousel or grid of links to related or similar collections onto any collection page:

### How it works

Palo Alto uses Shopify's Navigation menu system to bring custom menu items into any collection page and displays them as subcollections with a graphical image, collection name, description, and link.

### How to setup

Subcollections are already included with the default collection template, listed as a section called subcollection:

### Section Settings

### Adding collections

Use the link in the settings to create a navigation list, the rest is done right in your Shopify Admin under Navigation. Choose Add menu to create a new menu:

![](/files/PnOJtB5ENXYDG08b5lut)

Create a new menu with the same name as your collection:

![](/files/eSB2LRSAz01dk5LJsT8p)

For our example, we will be adding subcollections to our 'Espradrille' collection, our menu will be called **Espradrille** ,and the handle in lowercase: `espradrille`

Next, we'll add menu items, these will be the subcollection links that are displayed in the subcollection carousel or grid:

![](/files/CJMbUOJF0cIUMHw3n8fX)

{% hint style="success" %}
Create a new menu item for each collection that be listed as a subcollection.
{% endhint %}

Save your menu and your subcollections are ready to use.
