Stop scrolling when menu is open

How do I stop a full-screen navbar from scrolling when open?

Here is my site Read-Only:

Finsweet created a good solution for this.

It works in the beginning when the page is loading and then stops working after a few seconds.

Webflow - Narrative 1

The attribute of Finsweet needs to be placed on the Navbar element instead of on the trigger.

Also it’s probably good idea to delete the code you have in your page settings.

Did exactly as you said and it’s still not working. Is there anything else I could do to make it work?
