To display checkbox properties in the Property inspector, select a checkbox in a form. See also Adding an object to a form.
CheckBox Name Assigns a name to the checkbox.
Checked Value Sets the value of the checkbox when it is selected (checked). This is the value that is sent to the server-side application (for example, a CGI script) when the user submits the form.
Initial State Specifies whether the checkbox is selected or unselected when the form first loads.
