I would say: No kan do
Maybe you wanna build a work around with a popover with a portal containing the values:
- disable field access and set a popover over the field
- have a portal in the popover window sorted by 3. field. Every row with a button with script
• set Field value
• close Popover
This is a work around I'm specifically using für FM Go with Portal Filters and search-follows-input filter, since pop-up fields with endless lists really sucks
Sadly, the field in question already needs to be in a portal alongside other relevant fields. I assume I can't put an edit field with a popover in the portal when said popover already contains a portal? Pretty that's not allowed?
though you need to find a way to have field1 AND field2 combined to be used as Field 1 in Valuelist in order to use Field3 as the second value (not shown) to use for sort order.
Maybe a cross table with formula field f_Value1 = myTable::Field1 & " | " & myTable::Field2 can help.
Look out for other approaches with search query
- Virtual list
- Magic Value List
