I have a requirement to show elements belonging the Top Level item in my Module, but unfortunately i cannot identify the Top Level Item, since i am unable to capture any of the properties (or) Attributes of Top Level item.
Top Level item is defined in Level 1
Level 1 is parent of Level 2
Level 2 is parent of Level 3
When i choose Top Level Item in Level 1, then i should all the elements belonging to L3.
Can you explain what exactly you want to do with the Top Level in the level 1 list? Do you want to activate a filter if top level is selected? Or do you want to sum up all the children when top level is selected?
