Welcome to the forums Javad!
At the moment, no such gadget exists… So you need to get a little creative.
My personal test/R&D project has 70 pages over 10 categories. It can get a bit tedious using the drop down menu to navigate so I built my own navigation system into the groov View pages.
Here is a typical page from my project;
I have the main categories on the left under the Home button (no matter what screen you are on, clicking Home takes you to the top overview screen).
The subcategories then are along the top of the page.
The system has been in place and working really well for about 2+ years now.
Very happy with it, very intuitive and simple to build.
Hope that serves as some inspiration.
