Struggling with List Combine

Attributes

1

Hello,

I’m struggling to combine 3 collection lists into 1 using list-combine.

I would like to place my “Case Studies” & “Application Notes” lists at the bottom of the page into the “Resources” one above.

Here’s my read-only link: Webflow - Apoha 2026

Could someone please help me figure out what I’m doing wrong?

Thank you!

Hey @thesourdoughstudio!

This is definitely doable with fs-list-combine — it’s been verified in previous support cases too. Here’s the full setup to make sure everything is in place.

First, check your script tag. The attributes@2 script needs fs-list added directly on it:

<script async type="module"
  src="https://cdn.jsdelivr.net/npm/@finsweet/attributes@2/attributes.js"
  fs-list
></script>

That fs-list at the end is required for the combine feature to activate — easy to miss!

Next, on the Collection List element of your Resources list, add both:

  • fs-list-element = list
  • fs-list-combine = [your-identifier] (e.g. resources)

Then on the Collection List element of each source list (Case Studies and Application Notes), add:

  • fs-list-element = list
  • fs-list-instance = [your-identifier] ← must be the exact same value as your fs-list-combine

So if Resources has fs-list-combine="resources", both Case Studies and Application Notes need fs-list-instance="resources".

A few things to double-check:

  • Attributes go on the Collection List element, not the Collection List Wrapper above it — very common mix-up in Webflow!
  • The identifier must match exactly between combine and instance (it’s case-sensitive).
  • Important: fs-list-combine won’t run in the Webflow preview or designer — publish the site and test on the live URL.

Also as a side-note, you wouldn’t need 2 cdn scripts like so

<script async type="module" src="https://cdn.jsdelivr.net/npm/@finsweet/attributes@2/attributes.js" fs-scrolldisable></script><!-- Finsweet Attributes -->
<script async type="module"
src="https://cdn.jsdelivr.net/npm/@finsweet/attributes@2/attributes.js"
fs-list
></script>

You can combine them into one

<!-- Finsweet Attributes -->
<script async type="module"
src="https://cdn.jsdelivr.net/npm/@finsweet/attributes@2/attributes.js"
fs-scrolldisable
fs-list
></script>

Let us know how it goes after working through these steps! :flexed_biceps:

Thank you,

I double checked the implementation and it still doesn’t seem to be working.

My checkbox filtering also seems to have stopped working in the staging site (it is working fine on the live domain where I haven’t pushed any changes live yet).

Could someone please take a look?

Hey @thesourdoughstudio

I’ve checked out your read-only link & the site

I see 2 pages with the resources collection

On the main resources page only the first collection exists, The Resources collection
The other two, Case Studies & Application Notes are non-existent on the page

The second resources-copy page is setup correct
All three collections, Resources, Case Studies, & Application Notes exist on the page
The List Combine also works & successfully moves the list items from the last two collections into the main collection, the Resources collection

fs-list-field="tag" is also consistently present within all list field for filtering

I would suggest deleting the current Resources page & then make the Resources Copy page the main resources page

Let us know how it turns out

Thanks

Hey @thesourdoughstudio

If for some reason it still appears not to work on the resources-copy page that’s already setup correctly, try open it incognito or clear browser cache

Hi Jesse,

Thank you for replying - yes I am using the resources copy to test out the list-combine so as not to accidentally mess up the live resources page.

I had it right all along - just needed to look in incognito - thank you!

I have another query - how do I get the list instances to respect the sorting of the combine list?

Hi @thesourdoughstudio

Glad the resources page is issue is resolved!

About the list instances respecting the combine list sorting, could you make a separate post on that please, that way the whole team gets to see it and it can be handled asap

Thanks
