I have a group of item type. Under that group, I have the list of items. However, if the item has quality is bad, I suppressed it. Now, the scenario is ITEM TYPE 1 has 2 items which are ITEM 1, ITEM 2 and both of them are bad. Therefore, they are all suppressed and now ITEM TYPE 1 is empty. I want to suppress that ITEM TYPE 1 because it is blank now. I tried to count the number of items in ITEM TYPE but it returns 2 instead of 0 which I expected. Any solution for this?
