Dropdown filter doesn't work on live site (but works on editor)

Hello, after a few days working on a “simple” thing, aka a dropdown filter and a search bar, following this tutorial: https://www.youtube.com/watch?v=mTRSPNosLRw , I was finally ready to publish my website.

The filter works as expected on the preview, but not on the live site. The search bar works, but the dropdown only displays one option (the “All” option) instead of three.

Live site : https://www.alexis-veille.com/videos
The dropdown shows only “Tous les films” (“every films”) instead of “Tous les films”, “Direction de photography” (“Cinematography”) and “Réalisations” (“Films directed”)

You can see what happens in the editor (until 0’19) vs what’s actually happening in the published site (from 0’19)

My code is the exact same from the tutorial (at first I wanted to change the names of “Continents” and “Articles” but somehow it kept failing and didn’t work so I’ve ended doing the exact same thing)

I’d be so thankful to anyone who has an idea on how to fix this. I’ve tried different computers, browsers, and mobiles, the issue is the same.

Thank you.

Firstly, use the actual tutorial through Wix which gives you a fully built page in Wix Editor that you can view to see the page already made up and all the code done for you.

Otherwise, as you have used datasets, then make sure that you have synced the sandbox to live.

Hello,
Thanks, I apparently didn’t synced the sandbox for my dropbox menu, it’s fixed!
