sorry for the delay in replying. But the client didn’t respond and drives me crazy. 😡 😉
The menu now expands to the active page. Thanks for your help!
And now the client asks, if it’s possible to have that behavior in the collapsed mobile version to. So that the collapsed mobile menu expands to the the active page in a 3 level structure when the menu shows up (after tapping the hamburger to activate the menu).
