is it possible to show always the subpages/child menuitems of the first level element in the sidebar. For example I'm in the first level page (Parent1) and i want to list the second and third level in the sidebar (Child 1-3). And if I navigate in the second and third level (Child 1-3) I also want that all child pages are shown in the sidebar (Child 1-3).
Parent1 (for example custom posttype added to menu)
---Child1 (for example custom posttype added to menu)
---------Child3 (for example page)
---Child2 (for example page)
In my navigation menu i have also custom posttypes (added to the menu). How can i show them?
How can i add this functionality (without change in the core files of the plugins) or could update the section?
Thank you very much for you help
