Can I create a matrix that has four checkbox columns and one text column?

Thank you!

Unfortunately, the Matrix field can only have one input type.

If you wish to have different input types, you can try using the Configurable List widget, here's the link: http://widgets.jotform.com/widget/configurable_list
