Use radio buttons when you want site visitors to choose one option from a group. Clicking one radio button deselects all others in its group. After creating the form as described in Creating a Form:
In Page view, select the Radio Button tool from the Form toolbar.
Draw a rectangle on the form.
Set the Forms Radio Button properties.
Group name. Type the name for this group of buttons that’s passed to the script processing the form. This should be the same for all buttons in the group.
Value. Type the value passed for the button if the site visitor selects it.
Default. Choose
Selected to set the button’s initial state, which is returned as the response if the site visitor doesn’t change it. Remember that only one radio button in a group can be selected at a time and this only works if all buttons in the group have the same group name.
Disabled. Click this check box to disable the radio button on the form. The radio button will appear on the form, but site visitors will not be able to select it.
Dynamic select to add Data Source content to the radio button. Click the ‘...’ button to display the Data Sources dialog.
Style. Select a style to apply formatting to the contents of the selected box.
HTML. Click to open the Object HTML dialog so you can add your own code to the object’s generated code. See Accessing an Object's HTML.
To add a label to the radio button, use the Forms Field Label tool on the Forms toolbar. See Adding Form Labels.
