There is FTREE package in the Forms there. Also see "Manipulating a hierarchical tree at runtime" topic in the on-line help (especially FIND_TREE_NODE built-in).

Hello,

I still get that error message when no nodes are selected in the tree?
Does it means, that at least one node must be selected?
I didn't find anything about this error ...
But this doesn't disturb me.
And have one more small question according hierarchical tree:
is there any possibilities to remember a tree's expantion?
For example, when I go through the tree, I expand it under my needs, but when I execute_query,
I populate my tree again, when select the node in the tree, but it is all expanded, not just these previous braches.
Could you help?

You can know which node/nodes is/are expanded - you can move through the tree and store it to the variables.I would store Ftree.NODE_VALUE. After repopulating the tree you can once more go through the tree and expand node/nodes.
