Best way to present this on a form?

Here’s my requirement

I have a list of people’s names and my users will select a name, after they select it, there will be two fields for this name, Age (enter in a number) and a drop down list of cars (users will select a car). Basically I want to associate a name with a Age and Car.

For example, let’s say my list of people’s names has 10 names and users select 3 names then I’ll have 3 Age field and 3 cars drop down list. Each name will associate with Age and Cars fields . The worst possible case is they select 10 names then I’ll have 10 Age fields and 10 Cars drop down lists

I need advice on how to best do this on the front end so it will be clean and intuitive for users to use. These components are just html form components.

Thanks,

I would limit the selection to one at a time, hence showing the age and care fields for one person at a time. As a layout Id probably have a Grid to the left for selecting the person, and a FormLayout to the right.
