Each parent node has different number of child nodes.

Hi

It is not possible. You cannot set ENABLED/DISABLED or visible property to Node in the tree.

ty for the reply :) Smile

let me explain a scenario..there are two parent nodes called admin and employee...when admin logs in he should be able to select both the parent nodes and when a employee logs in he should be able to select only the employee node.

As you say let the nodes be visible and enabled...can i write a condition in when-node-selected or when-node-activated trigger to satisfy this criteria?? If so how do i write a code??

You can restrict the nodes by modifying the query that is responsible for loading the Hierarchical tree according to the logged in User type (Admin/Employee) .

sorry for late reply..thanks for the help :) Smile

I solved it..

if :global.v_admin='No' then

FTREE.DELETE_TREE_NODE(v_htree, delete_node);

end if;

i removed the nodes according to the login using this built-in..thanks a lot :) Smile
