(b) Use the Type drop down menu to select E-mail.
(c) Optional: Check the box to make the field mandatory.
(d) Click the Add button.
(e) Optional: Similar to the procedure followed when creating a new text field or text area, you can include a description, or change the default size of the email field by adjusting the width in the Display section (not visible in the below image).
(f) Optional: Use the Label display drop down menu to determine the relationship between the label and the field. By default, Above is selected, and the label will display above the field. Inline places the label to the left of the field. If you select None, the label will not appear.
