We have a client who uses the treeview component to move items from one parent to another. There are 18 thousand items in the selection list. Currently the treeview feature takes considerable time to come back due to how it works, to the extent that it is unusable. We were hoping that rather than trying to load 18 thousand values into memory every time our client tries to make a selection, the behaviour of this feature could be changed so that it only loads when a user is scrolling. I was hoping that you could assist us with a solution to this issue as our system is unusable without this capability. Is it possible to expedite a change in the behavior of this feature or are you able to suggest an alternative approach to help us resolve this issue?
