How to see hidden topology while weightpainting?

How to see hidden topology while weightpainting in wireframe mode?
Thanks for the answer guys!

Do you mean you want any hidden vertices to still be hidden when weight painting ?
You can enable face /vertex masking

Not sure if this is what you are looking for: in edit mode, select the faces that are hiding your topology. Press h to hide the selected faces and alt h to unhide. Then switch to weight paint and whatever you hid will still be hidden.
