To add this field click "Add Fields" located at the top of the Form Builder Module then select "Yes/No" under Selections:
The yes/no field is generally used for questions that require number only 2 responses (e.g. yes/no, gender). There's two types of configurations for the numbers field both can be found under the "Options" button. (Radio button = single choice. Checkbox = multiple choices). Change the title by click the title section (some html components can be used to alter the title)
Move the field up and down the form by using the click and drag tab on the left
Add a description to the field for extra directions (some html components can be used to alter the description)
Change the field status from mandatory to optional or back by clicking the asterisk. (Red = Mandatory)
Add additional settings to the field or delete it by clicking "Options". (Change styling will give you different types of ways to display the field. Copy field duplicates an entire field. Hide field from users will hide the field on the front end of the system. All admin will still be able to view hidden fields) As mentioned above, the Yes/No field allows you two settings. The first is radio which allows the user to only select one choice. The second allows the user to select multiple choices.
Clicking "Change" next to the Yes/No title will give you the option of switching this field into another type of Input field.
Click "That's it" once you're done with edits to save
