Hello,

I’d like to separate my two collection tabs using this animation setup from Finsweet: [List Tabs - Create Tabs with CMS Collections Lists in Webflow](https://finsweet.com/attributes/list-tabs), so that the products from the second collection appear only in the second section.

I’ve properly separated the two categories in my CMS page:

> **[Webflow - CTM](https://preview.webflow.com/preview/ctm-maquette?utm_medium=preview_link&utm_source=designer&utm_content=ctm-maquette&preview=0da25977894d85d14164b590d84ee026&pageId=682458238d909036108e838d&itemId=68245a33caa4a0f0244200d7&locale=en&workflow=preview)**

However, I can’t seem to get the filter to apply correctly, and the Icom products are currently showing up under the Motorola range:

> **[CTM](https://ctm-maquette.webflow.io/collections-de-produits/radios-portatives)**

I did add the custom attributes `fs-list-instance` with two different instance IDs, but the issue remains.

Could you please help me fix this by applying the correct filters?

Thank you so much,  
Romane

Hi @vedelromane!

I took a look at your page and I noticed some mistakes in the set up:

- Remove `fs-list-instance="Gamme 1"` from the element with class “Tabs Menu 2”
- Remove `fs-list-instance="2"` from the element with class `Collection List 4`

Fix incorrect attributes on both Tabs:

- On Tabs 2, change `fs-cmstabs-element` to `fs-list-element`
- On Text Block 3, change `fs-cmstabs-element` to `fs-list-element`

Let me know once you’ve made this changes or if you run into any issues!

Hello Pedro,

Thank you so much for your reply.

I just updated the mentioned attributes, however, it broke the tab animation.  
Could you please help me fix it?

here is the staging link updated : [Radios bidirectionnelles mobiles | CTM](https://ctm-maquette.webflow.io/collections-de-produits/radio-mobiles)

Thanks a lot,  
Romane

I’m sorry I missed this part in the last message.

Replace the CMS Tabs script with the new script:

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

```

And make sure all the Attributes are `fs-list-element`

Let me know how it goes!
