If I write:
rootNode.expand()
I can only get access to the children nodes of this rootNode, but can't get access to the grandchildren nodes of this rootNode. I have to write:
rootNode.expandChildNodes()
in order to acheive it.
Is there another way to obtain the grandchildren or further children nodes even if the tree is collapsed? other than using node.eachChild()
function?
I tried:
rootChildNode.firstChild
but it doesn't work.
ExtJS 4x has expandAll()
method on the Tree Panel component. This will expand every node recursively.
