Yes, you can include a blank value, this is given in the example. Just set the first element of the array to the value for the label "" and the value to an empty string
$values = array(
'Please make a selection' => ''
'label for value 1' => 'value 1'
);
@hube2 While this does seem to validate, it doesn’t give the user any indication whenever it is invalid. For example I have the following:
[dynamicselect* user-category id:user-category first_as_label class:text class:half class:mright "wpcf7_tax_listing_select"]
Left empty Contact Form 7 states:
Validation errors occurred. Check your information and submit again.
But the form neither border colors the field red as invalid or adds the Contact Form 7 class wpcf7-not-valid which leaves the user guessing which required field is empty.
