To filter and sort "multi-reference" collection items in Webflow, you can follow these steps:
1. Create a collection list: Start by adding a collection list element to your page. This will serve as the container for displaying the filtered and sorted collection items.
2. Define the data source: Within the collection list settings, choose the collection you want to display the items from. Set the filter and sort options for how you want the items to be displayed.
3. Filter by multi-reference field: To filter the collection items based on a multi-reference field, you'll need to use the "Dynamic List Filter" feature. To do this, add a multi-reference field to the collection you're working with.
4. Configure the dynamic filter: Click on the collection list element and go to the "Filters" tab in the right sidebar. From there, select the multi-reference field you created and choose the filter option you want to apply. For example, you might want to only show collection items that have been referenced by a specific item.
5. Sort the collection items: To sort the collection items, you can again go to the "Filters" tab in the right sidebar and click on the "Sort" button. Choose the field you want to sort by and select the sorting order (ascending or descending).
6. Style and design the collection list: Customize the layout and design of the collection list using Webflow's visual design tools.
By following these steps, you will be able to filter and sort "multi-reference" collection items in Webflow. Remember to save and publish your changes to see the filtered and sorted collection items live on your website.
