Macro Nested Children get paren

I need to get a childs parent node even if is nested 3, 4 or 5 levels deep. For instance:

root
- level 1
-- level 2
--- level 3
---- level 4
----- level 5

On level 2 I have a hierarchical viewer with transformations displaying all pages on level 3 and when a level 3 item is selected level 4 items are displayed in a nested <ul>. I only display 2 nested levels in the navigation but there could be as many as 5 levels below the level 2 page (where the hierarchical viewer is). When the user selects either level 3 or level 4, the css class is set to "current", which works as expected. When they select an item on level 5 how can I set the css class of levels 3 or 4 to "current" knowing that level 5 is still in the node of level 2, 3 or 4?

Right now I can use this

Convert.ToInt32(Convert.ToString(Eval("NodeID"))) == CMSContext.CurrentDocument.NodeParentID

to check 1 level above but this is limiting.

In the first cycle you will get the NodeParentID - using this ID you will check the NodeLevel. It may be little bit complex loop but it will work. Best regards, Juraj Ondrus

RE:Macro Nested Children get paren

I'm guessing I should create a custom macro for this. But I wonder if there isn't a method already for it because what I want to happen is already working on the CSS List Menu webpart. If I set it to only select 2 levels deep and there are 6 levels, if I check the option to "Highlight all items in path" it does so. Any thoughts on what that method is or how I could utilize that same functionality?

Hi,

The list menu is using the API. Your custom macro would use the same. But you can achieve it by creating a loop/cycle in the K# macro in the same way as in the custom macro code and then you will use properties the same as in the API. As I mentioned above. The NodeParentID and NodeLevel to check if you are on the levet you want to be.

Best regards,
