Hi @leomru,
What I have understood, that you want to give an option to your website visitor to click on the button to open a modal while scrolled down into the page.
If that is the case, I would suggest you to use the Header builder to create a sticky bar which will contain the Navigation Collapsed or other options given by my colleague in the above post.
Please follow the below steps to create the sticky header:
- Set
Off
the Sticky Bar
for the header. [ Screenshot 1]
- Duplicate the same Header bar with
Sticky Bar
On. [ Screenshot 2 ] replace the navigation element with the Navigation Collapsed or else.
- Set
Hidden
initially, so it will appear only when you scroll.

If that is not the case, and you are trying to point out something else, please provide a few more information like a screenshot with a marked issue or any video. It helps us to understand what you are expecting.
Thanks
