In the Form Editor, you can select multiple fields to duplicate or delete them at the same time. This increases the experiences and eases the effort to build the web forms you need.
In the layout of the editor, click on the first field. Now, hold the CTRL key from keyboard and select with your mouse other fields.
A counter will appear on the top-right corner of the layout. The counter shows the number of form fields you have selected.
Next to the counter you’ll find two buttons: Duplicate and Delete. Press the first button to instantly duplicate all the selected form fields or the second button to delete them at the same time. Each duplicated field will appear at the bottom side of the layout.
