Making a Dockable UI Menu for VR

Hi! I am a beginner with UE4 and I want to make a UI/menu for my VR level that would change the location and placement of specified actors in the level when toggled. I saw the ‘VR Integrator Radial and Dockable Menus’ in the market and I want to make a similar setup on my own.
Please point me in the right direction for such tutorials/documentations as I am absolute beginner.

Thanks!
