How to make a hidden list in PyQT5?

Question

PyQt

How in PyQT5 to implement such a list as on the left in the image? There is a similar QToolBox - but in it, no more than 1 page can be opened at the same time.

That is, so that you can hide, if necessary, all pages or open all at once, without restrictions

Create something like the Widget Box as in the Qt ... - here of course C ++, well, I think you can port it to python.
