After all the necessary fields are created, you can set the look of how they will be displayed, i.e. customize a form layout. You can customize the default web form by adding or removing web form elements.
In an application, click Form. Drag and drop existing fields from the left part of the window into the middle part of the window. Select a form element in the middle part, and specify field properties in the right part. Save the form.
