Blazor dynamically linked drop down to list box

This is the solution to a unique use case:

Our marketing department wants to be able to send out email promotions to users. That is simple enough. Additionally, they want to be able to select the recipients by some or all the following:

1. All
2. Name
3. City
4. Zip Code

In addition, they want to be able to select all matching users of a city or zip code or just the Point of Contact (POC) for the account.

Last requirement is that if Name is selected with POC no other users can be selected and vise versa. If the POC is not selected, the user can add names.
