How can I get these fields to one line?

I need to get the fields labeled “E”, “F”, and “G” moved to the same line (above) as A, B, C, and D. How can this be done?

Please copy and paste the following CSS code in your CSS tab under the Form Designer:

#id_32
{
  margin-left: 60px;
}

#id_20
{
  margin-left: -90px;
}

Hope this will work.

This image shows my end goal (the “list of comics” area with the comic title, issue, year, etc fields) listed on one line. Will ccs coding allow for this to happen?

The list of submission field from the screenshot is a configurable list widget. Please refer to the guide below that can help you with setting up a configurable list widget on your form.

If you want to receive only one entry, you may limit the configurable list entries from the widget settings. Please let us know if that works for you.
