How to hardcode set of value to a variable , depending upon another variable

Hi ,

Below my requirement,

I need to define 2 variable.

variable 1 - > vehicle_type - > It has static values like 2 wheeler , 3 wheeler , 4 wheeler

variable 2 → Vehicle_company - > This will be dependent upon on variable 1 ( vehicle_type).

If the vehicle_type is 2 wheeler , then it will select Honda, Suzuki, hero etc .
If vehicle_type is 3 wheeler , then it will select Bajaj, Piaggio etc .

How can I achieve this , Is there any where I can define the relation between the variable ?

Not sure whether I was Able to explain the requirement or not .
Thank you

Do you need something like this?

Hi.

We don’t have permission to add new plugin .

Is there anything that we can do without any plugin?

If you can’t add new plugins, use existing ones.

Which datasources do you use? Use their capabilities to make required variable mapping.
