How to check alot of nodes

[sdraper69]

I am looking at using fancy tree as a replacement for jsTree.

Whilst JStree does everything I want, the performance is very slow when ticking a lot of checkboxes at once. I wanted to do some tests to see how fancytree compared but I am failing at the first hurdle.

I have a tree created, with a lot of nodes and child nodes. (for sake of argument, let's say 2000 nodes, some 3 levels deep) I now want to pass an array of ids to become checked, and an array to become unchecked, but I am struggling with the documentation to even see which function I would be using to achieve this?

Of course, when an item is checked/unchecked it should affect any parents as you would expect (tristate etc).
Are there any demos of this behaviour with a large amount of data already setup to speed up my testing? If not any guidance would be appreciated.

A demo with the different select modes can be found here: http://wwwendt.de/tech/fancytree/demo/#sample-select.html

Some (partly outdated info here https://github.com/mar10/fancytree/wiki/SpecSelect)

Basic traversal is done using visit() and usually fast. There, callsetSelected() to update the status.

Finally call fixSelection3AfterClick(), or fixSelection3FromEndNodes() on the top nodes to fix the result.
