Click + Add field value option.

The field option entry field appears.

Enter the first value into the entry field, and then press Enter.

Every time you press Enter, a new entry field row will appear.

Continue entering values as needed and pressing Enter until you have entered all values you want to include in the list. 

A color is automatically assigned to each value. To choose your own color, click the color dropdown to the right of the value.  

The color picker appears.

Confirm the color by clicking a color bubble (1).  If you would like a custom color (supported on paid plans only), enter the custom hex value into the hex value box (2).

Choose whether the text overlaying the bubble will be white or black by clicking the color bubble above the hex value. Each time you click the bubble, the text color toggles between white and black.

Click Save inside the color modal to save the color option.

Repeat steps 3 - 7 until you have entered all values.  

Click the trash can icon to remove items you have mistakenly added.

Click the text of any existing value to shift it back into edit mode so that you can edit the text of the value.

Use the drag icon to reorder items in the list.

Click Save on the Edit field properties screen to save the single select field and all of its defined properties.

Click this option to sort the list of values you have entered alphabetically.   

🔔 If you enter new values, and you want them alphabetized, click this button after you have added all values.

If you do not want the value options to have colors, toggle this option to the off position. When this option is off, all values appear as dark text on white background.

If every row should have a value by default as soon as a record is created, specify the default value here. Users can change the value, but setting a default can help to minimize the number of null value records. 

🔔The default value text must exactly match an option in the list of values. In the example above, a likely default would be the value  New, which would allow all records that a user enters to start with a status of New.

If you enter any text into the Field callout textbox, the information (i) icon appears to the left of the field name, and the text you entered displays when users move the cursor over this icon. Enter text here if you want to provide information to help the user learn more about how to use the field.
