I have tried these options:
jQuery( document ).ready(function() {
jQuery("#adv_actions_shortcode").val("verhuur");
});
and
jQuery( document ).ready(function() {
jQuery("#adv_actions_shortcode option[value=verhuur]").prop("selected", true);
});
The url is http://makelaarcorrect.test.hetkanbeteronline.nl/woningaanbod-verhuur/
I must be forgetting something, anyone can help me out?
