Would like the ability to bind raddropdowntree using a webservice (I have a tree structure that has 15,000+ items) while still having the ability to enable filtering. Currently you can do one or the other.

when there are a lot of items checked, the RadDropDownTree displays the names of the checked items and an ellipsis, Unlike the RadComboBox which displays "X items checked" or "All items checked" if the list of checked items is too long. Please add an option for behaving like the combobox UX "[N | All] Items checked". Users do not understand this is a different control and they think it's a combo but unlike the RadComboBox they are getting a different type of behavior when selecting multiple items

1) Be able to get the level of a node in JS code
2) Have custom attributes that could be assigned to the drop down entries.
3) Force the tree of a selected node to be opened.
4) Be able to scroll to the selected node on opening the drop down for the first time (in the attached image I had to scroll quite a way to get the relevant node.)

Hi
Please add rtl support to RadDropDownTree.

Thanks

Two requests.

1. When filtering allow tree children to be unhidden if the parent matches the pattern. Maybe add filter by level (parent, child, both).

2. Add highlight capability to show all matching node filter patterns.
