That approach worked great, thank you! I’ve now got it working.
Do you have any suggestions as to how to approach the manual ordering of the categories listed on the card-single.php view? The difference is that not all categories would be shown on every card.
For example, one person might just have the PreK and K5 categories, while another might have K5, 6th-8th, and 8th-12th. It would be great to have them listed in the same order as the category select menu.
Appreciate your help,
