What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I'm not sure if I understood your concern correctly, could you provide us more details of your question or problem?
If you would like to populate the checkmark of the form using the form URL we can do that.
Here's an example: http://www.jotform.com/50396009629157?interiorSeats=Leather
For the field "Interior Seats", if you would like to select Cloth or Leather just add it to the URL. Here's how to prepopulate a field using form's URL parameters: http://www.jotform.com/help/71-Prepopulating-fields-to-your-JotForm-via-URL-parameters.
Do let us know if I misunderstood your concern.
