I tried - with irritating results.
Assume the following tree:
home (1)
|__main1 (2)
| |__sub11 (4)
| |__sub111 (8)
| |__sub12 (5)
|__main2 (3)
|__sub21 (6)
|__sub22 (7)
All these ressources have been assigned the same template containing this Wayfinder call:
[[!Wayfinder? &startId=`[[UltimateParent? &top=`3`]]`]]
Then the output will show:
- just the own children
in (2),
and in the children of (3), that is in (6) and (7).
- the whole tree
in (1),(4) and (5) - not being children of (3)
- sub111 as a child of itself in sub111
So that’s really a bit confusing.
At least the following worked to my intention:
[[!Wayfinder? &startId=`[[UltimateParent? &top=`[[*id]]`]]`]]
It shows only the own children (and grandchildren ...).
Kind regards
