Page widgets are reset if the dropdown is changed in forms

I have a use case where I have a set up Inputs to accept from the user. All Inputs are witin a form. As soon as the submit button is clicked there are some chartes are rendered based on the inputs.

The problem is when the user modifiy any of the input but haven’t prssed the submit button the page is reset to blank. I am looking a way that the page should alteast show the last submitted Inputs.

Any help is greatly appreciated.
Thanks
