Dynatree or Jquery UI Dialog slowing down after couple thousand members

Question

I have a simple application where I am displaying the tree list in a dialog box for the users to pick and have a little servlet in background for lazy loading. The problem happens for me when I click on one of the directories. This directory contains 4000+ other directories. The scroll bar becomes very hard to scroll down, slowing down measurably.

I have a solution to group things on the screen so that the users see the first couple characters of the directories and then slowly let them drill down. I was wondering if there is a simpler solution to this other than this thing I have in mind.

Answer 1

The solution I have done is actually similiar to this. I have created a pseudo hirearchy where none existed before. See this answer for an other question. How to render a large tree
