If you are working with a form that you would like to fit in a particular block on your website, but are having trouble getting the sizing right, we listed out some instructions below.
Changing the Size:
You can change the field size by clicking on the field you would like to adjust and choosing size option in the toolbar.
You can also change the width of the entire form from the builder as well. Select Form Width from the tool bar.
To Adjust Height of your Form using iFrame:
Delete the part of the code that says: onload='this.height=screen.height;'
Insert: height="NUMBERpx" (where NUMBER=the height of the area on your site).
