Yes, you can create a Collection List in Webflow that pulls in content from different Collections by using the Multi-Reference field type. This allows you to associate multiple Collections with each item in a Collection.
Here are the steps to do so:
1. Go to your Webflow Dashboard and open your project.
2. Click on the 'Designer' button to access the design interface.
3. Create a Collection for your products if you haven't already done so. In each product item, add a Multi-Reference field type called "Categories" or something similar.
4. Set up your individual Collections for each category of products. Add the necessary fields to each Collection to define the products and their details.
5. In your 'View All Products' page, add a Collection List element and bind it to your primary Collection (the one that contains all products). This will display all items from that Collection.
6. Customize the layout of your Collection List using the layout and styling options available in Webflow.
7. To create a filter, such as 'Products under £100', you can add a separate Collection List element on the 'Products under £100' page. Set this Collection List to be filtered by the relevant field (in this case, price). Use the "Filter" property of the Collection List to specify the condition for the filter.
8. Customize and style this filtered Collection List to suit your desired display.
By using the Multi-Reference field type, you can associate each product with multiple Collections, allowing you to display products from different categories in one list or apply specific filters based on your requirements.
Remember to publish your changes for them to be live on your website.
