This seems to work fine, a few issues such as once a Campaign has been assigned, it cannot be unassigned if it is the last Campaign Assigned to that post (basically there has to be one campaign assigned at least)

This shows an accordion which holds checkboxes of the Campaigns (to allow people to unassign a Campaign). Is there a way to convert this into a dropdown?

Thanks Morgy however this shows up blank, once again I tried some tweaks but no joy.

Thanks for clearing that up bcworkz! I think the autocomplete feature would really help as there will end up being a lot of campaigns (possibly hundreds eventually) and could be tedious to scroll through them.

I’ve seen a few plugins and tried them out but they’re either outdated and not working or don’t have the ability to use custom taxonomies, which is why I thought some custom coding might be need as you say.

Thanks Jason

Thanks for your reply Jason,

I’ve tried this and can’t seem to get it to work…

<tr style="border-bottom:1px solid white;">
    <td class="tg-031e"><img style="padding:0px; margin:0px; vertical-align: middle;" src="/wp-content/uploads/2016/05/designlogo-upload.png"></td>
    <td class="tg-031e"><a onclick="SlimStat.ss_track(event, 100, jpeg_downloaded)" style="text-align:center;" class="download_image" target="_blank" href="<?php the_post_thumbnail_url( 'full' ); ?>" download><strong>DOWNLOAD</strong> as a jpeg</a></td>
  </tr><br>

Is this correctly entered?

Kind Regards,
Will
