Dynamically preselect an HTML radio button
Dynamically preselect an HTML radio button when a record is displayed in the HTML form in a browser.
Before you begin, you must create the form in a ColdFusion, PHP, or ASP page, and insert at least one group of HTML
radio buttons (Insert > Form > Radio Group). You must also define a recordset or other source of dynamic content for
the radio buttons. Ideally, the source of content should contain Boolean data, such as Yes/No or true/false.
1 In Design view, select a radio button in the radio group.
2 In the Property inspector, click the Dynamic button.
3 Complete the Dynamic Radio Group dialog box, and click OK.
Set the Dynamic Radio Group dialog box options
1 In the Radio Button Group pop-up menu, select a form and radio button group in the page.
The Radio Button Value box displays the values of all radio buttons in the group.
2 Select a value to dynamically preselect from the list of values. This value is displayed in the Value box.
3 Click the lightning bolt icon beside the Select Value Equal To box and select a recordset that contains possible
checked values for the radio buttons in the group.
The recordset you select contains values that match the radio buttons’ checked values. To view the checked values
of the radio buttons, select each radio button and open its Property inspector (Window > Properties).

Validate HTML form data
Dreamweaver can add JavaScript code that checks the contents of specified text fields to ensure that the user has entered
the correct type of data.
You can use Spry form widgets to build your forms and validate the contents of specified form elements. For more
information, consult the Spry topics listed below.
You can also build ColdFusion forms in Dreamweaver that validate the contents of specified fields. For more
information, consult the ColdFusion chapter listed below.
1 Create an HTML form that includes at least one text field and one Submit button.
Make sure every text field that you want to validate has a unique name.
2 Select the Submit button.
