Hi, I had one more complication, UI related. So I have made a multi-box with a field 'A' having three levels 1, 2 and 3. Now as multi-box works, I can filter the data by selecting 1,2 or 3 or a combination of these levels. My requirement is that if someone selects 2, 1 should automatically be selected and if someone selects 3, 1 and 2 should be auto selected. Is this possible?
