This form shows how you can keep your HTML simple, yet add lots of RIA-type effects to your forms. In this example, the <label> tags are used to highlight which field has focus. Notice since we're using the <label> tag, you can also click on the label to set the focus to it's cooresponding form field.
qForms does this by parsing the DOM looking for <label> tags that have been assoiciated to a specific form field. qForms will automatically assign an "id" attribute to form elements which don't have the attribute natively assigned to it.
This form also uses the dhtml.js addon, which overrides the default error handling mechanisms and will display errors using the DOM.
