Why is the filtered checkbox not working when I click on each profession in Webflow? And why is the collection list I created in the multi-reference field not showing in the Collection List I created, requiring me to use options for the collection?

If your filtered checkbox is not working and the collection list connected to a multi-reference field is not displaying, it likely involves issues with Webflow's filtering system and the limitations of multi-reference fields.

1. Filtered Checkbox Not Working

• Checkbox filters don’t apply automatically in Webflow like in custom-coded setups—you need to use custom JavaScript or a third-party plugin (like MixitUp or Jetboost) to make filtering work based on checkbox selection.
• Just placing checkboxes on the page doesn’t activate dynamic filtering unless you:
• Program behavior manually using JavaScript.
• Use Webflow-native filters only in the Designer’s Collection List settings, which won’t respond to UI elements like checkboxes.
• Webflow’s filtering through UI is static, meaning it doesn’t update live based on user interaction unless external scripts are involved.

2. Multi-Reference Field Not Working in Collection List

• Multi-reference fields cannot be used directly in Collection Lists the way single-reference fields can.
• If you tried dragging a Collection List into a Collection Page and binding it to a multi-reference field, it won’t automatically link unless:
• You're on a Collection Page that supports that relationship.
• You add a nested Collection List, and the multi-reference field supports nesting (up to 5 items shown total).
• For large multi-reference items, you must use an external workaround—or display the connected data using Options fields or plain text references, depending on your use case.

3. Option Field Used Instead of Collection List?

• Some users replace multi-reference fields with Options fields because:
• Options fields show their values directly without needing a separate collection.
• They allow conditional visibility and filtering in Webflow natively.
• You might have done this because Webflow does not natively allow filtering over multi-reference fields in the UI/Designer.

Summary

The checkbox filter isn’t working because Webflow does not support dynamic filtering via checkboxes without custom code or tools like Jetboost. Also, multi-reference fields don’t show inside Collection Lists unless used in a nested Collection List on a valid Collection Page context—and even then, only show up to 5 items. Consider using a third-party tool for filtering and rethink whether a single-reference or Option field suits your data better.
