NodeExpansion Handler - Collapsing Nodes

[bgreenhouse]

Hi Guys

I want to make my tree (FTree component) so that when you open a node, all other open nodes close. I thought it would be fairly simple, set up a nodeExpansionHandler that either

1 - makes a global variable remembering the node that is open and then closing that variable the next time it is invoked. or

2 - cycling through all the nodes and closing all that aren't the one that was opened.

However, I can't find any method or property of a node that lets you close it. I try to use the

setIsOpen

method, but that just puts the closed icon beside the node, but doesn't actually collapse the branches.

Any suggestions/links?

Thanks

you have probably done this already but i would edit the component and find the code that allows manual collapse (by clicking). it must be a function. the methods used in that function may well provide the clue.
