Beginning Drupal 8

Chapter 5 ■ Content Types
Figure 5-20. Setting the widget type to “Check boxes/radio buttons”
After clicking the Save button, the new field is ready for use, as shown in Figure 5-21. You’ll note that
Drupal added a third option to our list, the N/A option. Since we did not check the “Required field” check
box for this field (see Figure 5-19), Drupal automatically inserts the N/A option because a visitor may wish to
not select an option. If you want to remove the N/A option, check the “Required field” check box and Drupal
will remove that option from the list.
Figure 5-21. The “Type of Seating” radio buttons field
Check Boxes
Check boxes are similar to radio buttons but allow the user to select more than one value from the list.
We will now expand on our Event content type by adding a list of check boxes that addresses special
accommodations available at this event for attendees with disabilities. We will create check boxes that
specify whether audio-assisted devices, visual-assisted devices, and wheelchair seating are available for this
event. To define the list of check boxes, return to the Event content type’s “Manage fields” page and click the
“Add field” button. Select “List (text)” from the “Add a new field” select list (refer to Figure 5-17) and enter a
title of “Assistance” in the Label field (see Figure 5-22).
