# Sub-collections

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

![Promote other collections on your collection page](/files/-MhWCt1dTSGsuDBiestT)

### How it works

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

### How to setup

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

![](/files/-MhWF_7ve0TlQ-BaMAmK)

Settings for Subcollection:

![](/files/-MhWGKAr83eWx-M7U1T6)

### 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/-MhWI3CjrMlG9JWRk6Ku)

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

![](/files/-MhWIBb2JYK-LGD5s4NZ)

For our example, we will be adding sub-collections to our Necklace collection, our menu will be called **Necklaces** and the handle in lowercase: `necklaces`

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

![](/files/-MhWInFEEtLgDtSJvBxG)

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

Save your menu and your sub-collections are ready to use.
