I am trying to Filter a dropdown within my Custom Page. In the end something like this has to be achieved:
-> User clicks on Ribbon Bar button in Dynamics on a contact
-> Account ID is retrieved via JS and given to Custom Page via "navigateTo" (varRecordId in Power FX)
-> Custom Page Opens in a Dialog
-> Only Opportunities of the given account can be selected by User
-> Some Business Logic on Button Click
Does someone have an Idea how to Filter the Dropdown correctly in Power FX? I tried almost everything but I am not able to make it work:
