ExpandAll Function is extremely slow.

Hi,
I recently started using cooltree and i have implemented checkboxes at each level. I have 3 level tree, but the number of nodes is large (>1000 nodes in all).
I want to expand all the nodes at load, but this is taking forever. I also have ExpandAll and CollapseAll buttons. In the subsequent hits, the expandAll is pretty fast.
Is there any way I can speedup the expandAll on load?

Rest all functionality is working fine.

You're hitting browser's performance limits. There is no way to speed up global expansion.

Please, think twice:

1. If you're expanding all nodes at load time, then you actually don't need dynamic expansion/collapsion - you can use plain HTML tree.

2. Hardly anyone wants to see 1000+ nodes (and checkboxes) at the same time.

Do you think if I get the prof version, it will speed up the performance? I see the prof version has some added features.

I repeat: you're hitting browser's limits.
