I've 10 test fields, in-front of each text field there are list item (separate list item)
for each list item, element list is given below
at position C-Delivery date is assign (or selected by user) but at position E - Delivery date is again assign. In such situation i want to prompt the user the value is already selected. How should i go about this? Should i design button for validation if yes the what should be the code? or should i go with when-list-change and what should be the code?
THe most user-friendly way would be to remove elements from all other lists when they are chosen once. You would have to have a WHEN-LIST-CHANGED-trigger on all listitem and populate the the listitems accordingly.
