Defining a TreeSet Collection
By default a TreeSet Collection is displayed in the tree, and all of its nodes are visible. If needed, you can hide:
• the entire TreeSet Collection
This is useful for example to define tree items that are used as filters but do not need to appear in the tree display.
• the nodes of the TreeSet Collection that do not have any child
You can define a TreeSet Collection with a loop, which enables to add a recursive definition.
Hiding a TreeSet Collection
See example How to Hide a TreeSet Collection?.To hide a TreeSet Collection:
1. Access the TreeSet Definition.
2. Display its Definition page.
3. Select the TreeSet Collection you want to hide.
4. In the right pane set Visible parameter to "No.
Hiding nodes with no child
By default, any node of the collection is displayed, even if a node has no child. You can hide nodes with no child.
To hide the node with no child of a TreeSet Collection:
1. Access the TreeSet Definition.
2. Display its Definition page.
3. Select the TreeSet Collection for which you want to hide nodes with no child.
4. In the right pane set Must have a child parameter to "Yes".
Adding a loop to a TreeSet Collection
With a recursive hierarchy, you can add a collection loop to the TreeSet Collections.
To add a loop to a TreeSet Collection:
1. Access the TreeSet Definition.
2. Display its Definition page.
3. Select the TreeSet Collection for which you wnat to add a loop.
4. In the right pane, in the Recursive Definition section define the loop:
• in the TreeSet Collection loop field, select the "<TreeSet Collection name>".
• (optional) in the Maximum loop depth enter the number of levels you want to add.
