LiveCycle - Hidden repeatable SubForm becomes visible when a "MO" is selected. However, if "MO" is changed to "KS" or any other state within the repeating rows, that visible SubForm should reset back to hidden.
to be able to do so, you should have your dropdown list within a repeatable subform which should be considered as your main index, so you may have 5 drop down lists with each respectively 1 subform comes with it.
So let's say your dropdown list is inside a repeatable subform, and you have another subform underneath that is linked to that drop down list
in your drop down list exit event, you should have if statements to determine which value has been selected, and then depending on the value selected you hide or show the subform
Okay, then you should iterates through each of the rows to find if you have a drop down list with MO selected, and if you have at least 1 value MO, then you show your subform, otherwise you hide the subform
