How to open Nav Menu and highlight the active menu item on page load?

Hello.

On a website I use the BricksExtras Offcanvas (template) and the standard Bricks Nav Menu with the Multilevel function.

When I am now on a subpage, the menu should be open and the subpage should be highlighted (screenshot 2). However, the menu is always closed (screenshot 1).

Am I missing a setting or is this functionality not included in the Nav Menu?

How did you solve this? Does this work with the Nav (Nestable) Menu?

Thanks in advance
