Can we control choices (in drop down) of 'List' type field based on some referenced field's Choices

[HitSnow]

Hi,
I have Sample form where I have 'List' type field test_key, I created choices in it using dictionary. (TestA; TestB; TestC; TestD; TestE; TestF; TestG; TestH) and I have another field on same form which is referenced field name 'Test' and on referenced field's test form has a field name test_type which has choices (Test1; Test2; Test3; Test4).

There is mapping for choices
{ 'Test1' : ['TestA', 'TestB', 'TestC', 'TestD', 'TestE', 'TestF', 'TestG'],
'Test2' : ['TestE', 'TestF', 'TestG'],

'Test3' : ['TestA', 'TestB', 'TestC', 'TestE', 'TestF', 'TestG'],
'Test4' : ['TestA', 'TestB', 'TestC']
}

I have requirement when Sample initially loaded, user can only see selected option/choices in dropdown of List as per Sample form test_type field chosed option,

Ex. If test_type field has 'Test4' selected, then when Sample form onloads then in test_key field list dropdown user should see only those choices to be multi select ['TestA', 'TestB', 'TestC'], 
similar when 'Test2' selected then user should see only these choices in List dropdown ['TestE', 'TestF', 'TestG'],
User should not see all choices to be select for multi select.

I tried I am getting all choices in test_key field drop down for any selection in test_type field. Could anybody please suggest any suggestion.

Thank you in advance.

Hello @HitSnow 

List field type choices aren't controlled the same way as they are for choice field type.

Please share your code

Hi @HitSnow , 

Please share the code you have written for this along with some screen shot of both field.

We need to configure the mapping of both fields somewhere in system, you can try with Choice [ sys_choice ] for all 

test_type values and add the dependent value as test_key value.
