An easy way to make a tree-browse

[MarioG]

Hello Mr Rao
I'm using a Tree and it's good
I'm using the same oTree:MakeTree() that your sample
but when i send oTree:CollapseAll()
it collapse the app

Error occurred at: 20/11/2019, 19:37:33
Error description: Error BASE/1004 Message not found: TLINKLIST:COLLAPSEALL

what is wrong?

Sorry Mr. Rao
I 'm seeing in the source; and not exist a Method CollapseAll()

but when i send oTree:CollapseAll()

There is no CollapseAll() method.

Use oTree:Collapse()
