Ability to hide some items in tree
 

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.

you could achieve sth like that by saved search, with the difference that items show in search results pane instead of tree

quant,
Yes, I now, but I think the display in the tree is more useful. I will can create many tree from my one tree
