I'm using contact form 7 and here is the actual contact form 7 code to display the select drop down
<div class="select-wpr">[select* program id:program first_as_label required "Choose your program of interest"]</div></div> <div class="full-width"> <div class="select-wpr">[select* campus id:campus first_as_label "Choose campus"]</div> </div>
Where can I go and modify the actual select drop down options? I want to add
<optgroup> to the select options but can't find where to go and modify that. Where is that located in wordpress?
