Yes, it is possible to link a Webflow CMS collection list to another CMS collection. Here's how you can achieve this:
1. First, make sure you have created the two CMS collections you want to link. Let's call them Collection A and Collection B.
2. In Collection A, create a reference field (or a multi-reference field if you want to link multiple items) that will hold the items from Collection B. To do this, go to the Collection settings for Collection A, click on "Add Field," and select the "Reference" or "Multi-reference" field type.
3. Once you have created the reference field, you can link it to items from Collection B. In the Editor or Designer, open an item from Collection A, and use the reference field to select the corresponding item(s) from Collection B.
4. Now that you have linked items from Collection B to Collection A, you can display them in a Collection List. In the Designer, add a Collection List component to the page where you want to display the items. Make sure you select Collection A as the data source for the Collection List.
5. Customize the Collection List layout and design as per your requirements. You can access the fields of the linked items from Collection B within the Collection List by using the binding options and pulling data from the reference field.
6. Publish your site to see the Collection List displaying the linked items from Collection B.
By following these steps, you can establish a link between two CMS collections in Webflow and display the linked items in a Collection List. This can be useful for creating related content sections, displaying related products, or any other scenario where you need to connect different collections of content.
