How can I categorize submissions?

We run a dance studio registration with your program where our clients select which specific class they would like to register in. Is there a way to automatically sort submissions based on their class selection?

You can sort them in the form submissions page by clicking the column names in the data grid.

Example:

If you want a more advanced sorting, I'd suggest downloading your form to Excel. This way you have more controls over your data using your Excel application.

Alternatively, if you also want a calendar report out of your form submissions, check this guide http://www.jotform.com/help/249-How-to-create-a-Calendar-Report.
