Ability to hide some items in tree

[MihailCherkass]

I would be glad if I can hide some item in the tree depend on a state of a toggle button and depend on some attribute. For example, firstly I set an attribute 'Visible1' to an item1, an item2, an item3. Secondly I set an attribute 'Visible2' to an item2 and item3. Third I assign a 'toggle_button1' to attribute 'Visible1' and 'toggle_button2' to attribute 'Visible2'. Now I can set the state of visible the items in the tree.
