Specify an invalid value
You can specify a value that will register as invalid if the user selects a menu item that is associated with that value.

In the Property inspector (Window > Properties), enter a number to use as in invalid value in the Invalid Value box.

Customize the Validation Select widget
Although the Property inspector enables you to make simple edits to a Validation Select widget, it does not support
customized styling tasks. You can alter the CSS for the Validation Select widget so that you can create a widget that
is styled to your liking. For a more advanced list of styling tasks, see
www.adobe.com/go/learn_dw_spryselect_custom.
All CSS rules in the topics below refer to the default rules located in the SpryValidationSelect.css file. Dreamweaver
saves the SpryValidationSelect.css file in the SpryAssets folder of your site whenever you create a Spry Validation
Select widget. Consulting this file is helpful because it contains commented information about various styles that
apply to the widget.
