How to add references

I would like some type of variable drop down in a form where users can add references.
E.g. a prompt, “List up to 3 references.”

And then up to 3 pairs of fields asking for (Name), (Phone number)

What’s the best way to structure the base and form for this

You’ll create your columns/fields for each pair. For example;

Name1 | Phone1 | Name 2 | Phone2 | Name 3 | Phone 3

Each piece of information collected will need its own field.
