Premium Campaign Selection with Mutual Exclusivity and Limit

Solution: For premium campaigns, there will be two dropdown lists, each allowing for a single selection. There needs to be mutual exclusivity between each campaign. For example, if campaign 'A' is selected, campaign 'B' cannot be selected, and there should be a limit on the maximum number of premium campaigns that can be selected.

On the other hand, for coupon campaigns, there will be multiple checkboxes, allowing for multiple selections.
