Ah yes I see what you mean. The theme can only rearrange parent categories though, not child categories. To rearrange the categories, go to your menucard page in the admin area, and scroll down to where you can select the categories for your menucard. You can drag and drop those checkboxes in the order you’d like. Save the page and check out the result 🙂

I hope this is what you’re after!

Cheers!
