Hello. Tell me who knows, I fight the second day, re-read already all that is possible.
Have a TreePanel and a textfield.
When the user enters something in the text box, the tree should be filtered and leave visible only those nodes whose title contains the entered text.
Similar situation with the grid was solved simply — filtering, store. But TreeStore has no method filter. How to hide the node. The network has found several solutions, but they were all for ExtJS 3.
Question actually in how to filter a TreeStore on the client or how to hide tree node (will filter itself then). The impression that I fantastically blunt, the problem must be solved by some simple and understandable way.
