we are using grouplist as a replacement of tree. That works good, the only thing I observed that it isn’t possible to select an item with subitems (It doesn’t change the color and dosn’t fire the onAfterSelect event).
You can’t select the group-item by clicking on it, because by default clicking will open that level.
But in same time something like next
$$('mylist').select("group 02")
will select any item, including “parent” one.
The second part of problem - parent items was not purposed for selection, so they just has not styles for selected state, which why they do not change color in selected state
