I want to be able to run those type of functions on the actual children that are there in the designer e.g. the ‘containers’ of the repeater (not known by that name anymore in EditorX though, now they are items), the boxes I’ve added to the repeater, … But since there’s no such property, it’s only possible when you add them to your repeater.data using itemData or something. If you don’t do that, you cannot easily access those ‘children’.
