Enhanced Pre-Population
You can now pre-populate nearly any type of item on your form. We have expanded the items available for pre-population from fill-in-the blank style items to now include Check Box Items, Radio Button Items, and even our sophisticated Matrix Items. You can choose to pre-populate your form using a special link or via JavaScript settings if you embed your form in a page on your site. We have also added the ability to pre-populate based on the item’s position or by its unique ID.
A popular use of this feature is to fill in a hidden field on the form for tracking purposes. Visit the documentation page for more details.
