I found the instructions here in the forum on how to Automatically populate a dropdown with post titles and it works like a charm, does what I need....
Except that it doesn't support validation if I make that text field (that gets replaced with the dropdown) a required field - the problem is in this line:
11 //Adding initial blank value. 12 $items = array("text" => "", "value" => "");
While I have entered the default text I want ("Please select your product"), and left the "value" => "" blank so that there should be no value (which should trigger an error on validation), the plugin still puts in the text as the value, negating the validation.
What can I do to make sure that the value stays blank and that the field is validated?
