Fill out a section multiple times

Is there a way to fill out a section multiple times ? 

For example -

1. we are doing a registration form for parents for their children

2. ask how many children they are registering

3. if possible would like to have the children sections be available to be filled up the number of times indicated in #2.

Thanks so much. 

Yes, that possible by using hide/show conditional logic.

Guide: How to Show or Hide Fields Base on User's Answer

For example, you have a field for 10 entries. Now, since you have a field for 10 people/entry, you will then hide/show these fields based on your users' answers.

You can use a dropdown to ask your users how many people they want to add.

You can also use the configurable list widget, it has the option to let users add multiple entries.
