Populate one multi select field from another multi select field in same form

Question

Hi,

Happy Friday!!

First multi select dropdown(A) displays up to 15 values and based on selection, I need to display values in second multi select dropdown(B). Both the dropdowns are in the same form. There is no DB data involved. The field B can have up to 50 values that need to be filtered based on selection from A. Please advise if multi select dropdown is correct choice for field B and also how to apply filter on 50 values based on selection in field A. Thanks.

This works for any number of options.

In your case (I suspect the Field A is also a multi-select)

Option1:true AND Option2:true Apply filter *

Option1:true AND Option2:false Apply filter that shows values for Option 1

The question is, how do you know/define the values that you want to show for Option 1 in Field B

Thank you for your response. This approach doesn't work when you have more than two options to decide the filter.

For Ex:

Field A : Option 1, Option 2

Field B(Multi select): We have to code for three scenarios to apply filter to values

Option1:true & Option 2:true --> Show all values(up to 15)

Option1:true & Option 2:false --> Show values for Option 1

Option1:false & Option 2:true --> Show values Option 2

I have Field C that need to display values based on selected options in Field B. Can you suggest an approach to address this situation instead of coding for combination of 15 values?

OK, so it is about our app, ConfiForms

You can have dependent dropdowns or any other choice based fields - see this page https://wiki.vertuna.com/display/CONFIFORMS/ConfiForms+Field+Definition+Rules#ConfiFormsFieldDefinitionRules-ApplyFilteronafield
