How to set a class for a block in pdomenu, provided that it has children?

Question

MODX

Hello! Tell me please! Completely broke his head. Nowhere did I find information on pdomenu for modx revo.
How to set the class "has-sub" for the menu item block, only for those that have children. For those who do not have descendants, this class should not be inserted.

Already tried &hereClass=`has-sub`, &innerClass=`has-sub` etc.
But it doesn't work.

Sample structure.

--- Insert has-sub here because it has descendants

Item1

Office
Production
Advantages



--- No has-sub inserted here, no descendants

Item2


--- No has-sub inserted here, no descendants

Item3

Answer 1

Try to explicitly specify the class in the chunk specified in the `tplParentRow` parameter, this is just for the item with descendants
