Will unique sessions work If I host the form on our website?

Will unique sessions work if I host the form on our website? Looking to keep the "save" functionality but also do a little bit more customization, like adding an input mask to a column of text boxes inside the Input Table widget, which I can't do in the JotForm editor *shakes fists at sky*

No, the saving data before submitting through URL session only works with the direct link of the form. It will not work with the embedded version. Let us know if you need more help.
