### What problem is your feature request going to solve? Please describe.

I would like to be able to add custom input fields to the checkout widget for woocommerce.

Let's say I'm selling swimming lessons where 1 package deal includes training 5 people at the same time, then the buyer should be able to add the information (name, age, etc) of each individual that will be included.

### Describe the solution you'd like

Be able the add input fields with custom placeholder and labels (also types text,number,email) and possibly a + sign where the same fields are automatically recreated if information of multiple people are going to be added to the purchase.
