How to place multiple fields on a row? When you click on a field in your Form Editor, you’ll see three icons: the blue icon for Duplicate, the green icon for Resize and the red icon for Delete. Use the last one to make more fields fit on the same row.
When you click the Resize icon, the Resize box shows up. Here, you can specify the Field Width and the Field Height. Naturally, the total width of fields per row should equal to 100%.There is another very important aspect: the height of fields on the same row should be equal, in order for that row to look neat.
