Placing a Check box field on an app form creates a field that allows users to select one or more options from a predefined list.

All of a Check box field's options are displayed and can be selected on the New record screen or the record editing screen. You can specify whether options are listed vertically or horizontally from the Form settings.
Only the options that have been selected are displayed on the  Record details screen.

You can also create a Check box field with only a single option so that users can select whether or not a certain option applies.

Specify the field name. The field name is displayed as the label of the field in the app.

Selecting the Hide field name checkbox hides the field name on the following screens.

• The New record screen
• The Edit record screen
• The Record details screen
• The screen for printing a record
• The Form settings screen

Selecting the Required field checkbox makes specifying a value mandatory.

Enter the name of the choice option. You can specify up to 1,000 options, and each option name can contain up to 128 characters.

To add fields, click the Add icon (plus sign) to the right of the input fields or press the Enter key when the last field is selected.
To delete fields, click the Delete icon (minus sign) to the right of the input fields.

To change the order of fields, drag and drop the "Drag to reorder" icon (arrow-shaped) on the left side of the field.

Select whether to list the options horizontally or vertically.​​​​
On mobile devices, options are displayed vertically, regardless of which setting is selected.

Sets the default value for the input field.
If you select this option, the field will be selected by default on the "Add record" screen.

This is the code used for specifying the field in formulas or APIs.

Use Check box fields when you want to make it possible to select one or more options from a list.
For example, you can use a Check box field in a survey app to let users select one or more reasons for visiting your store.

You can also create a Check box field with only a single option so that users can select whether or not a certain option applies.
For example, you can add a Check box field in a sales order management app and use it for selecting whether or not payment has been received.
