I want to allow users to change dropdown fields only if some other input fields are entered.
Is there any validation that can be done here. onOptionChange wont allow to have validations, irrespective of the option change it will allow users to change.

Also can I assign a value like this dropdown1.selectedOptionValue ='xyz'

#

eventhough it allows me to do. It wont get reflected in the frontend

Hey you cannot directly assign values to variables, it won't trigger a change. Store a value in the appsmith store and then use that value in the selectedOptionValue like {{appsmith.store.dropdownValue}}. Please check this video it will help - https://www.youtube.com/watch?v=UUvJn8oWqNs
