onClick pop-up

[Kaczucha]

Hi
I need to create custom menu in my top navbar. I've created a menu using home -> navigation -> add navigation.
Now I need to create a script/look for addon to make pop-up after clicking exact element of navbar ( something like in screens below ).
Can someone help me please?

Maybe this is the right addon for you it can open links in popup should also work with your script

He can change behavior of that navigation item by adding data-xf-click="overlay" to the link. Then it will open in a popup.
