This property is ignored if an External Type is specified for the form. In this case, the ability to search is determined by the searchable property of the type itself | SEARCHABLE |
| Display Type | Display the radio buttons either horizontally or vertically. Selecting horizontal may generate a confused layout, depending upon the length of the various display values next to each button | TYPE |
| Options | The values to be included in the group. Use the popup editor provided to set the Value and Display value for each radio button in the group. These values may be hard-coded (fixed) or dynamically loaded from a datasource. Hard-coded values can be entered using the grid provided on the 'Fixed' tab of the popup editor. Alternatively, they can be supplied as comma-separated values (value,display) via the 'Fixed (CSV)' tab, each row representing a single item in the list. Dynamically loaded values are set via the 'Datasource' tab of the popup editor. Typically, specifying the table, value, display and order by column names in the boxes provided will generate a suitable query. A custom query can be entered by expanding the 'Advanced' section; it will use any names set in the above boxes to generate a starting query. This custom query should select the value into a 'DataValue' column, and the display value into a 'DataDisplay' column. For example: Note that as options are stored as a comma separated list, the values cannot have commas in them | OPTIONS |

| Handlers | A JavaScript function that is executed client-side whenever the page loads, or the field value changes. This function is useful for modifying the values of other fields based on an entered value | HANDLERS |
| Read Only | Display the field as read only | READONLY |
