I'm designing a form for leaving contact information—ideally email and phone number, with both being optional (but requiring at least one entry).

What are some best practices for such a form?

  • You can have radio or toggle with "Whats your perfered contact method" and based on the answer show field below with phone or e-mail. – xul Sep 26 at 15:58

The possibility I see: Create a two divs with icons and nice communicate that's inform about advantages of every option.

I think on this case, toggle, when div clicked, it should display input, which user fill.
