We are trying to create a gallery of interesting uses of SQL that most people don't readily know. The repo for this gallery is located here: https://github.com/pavanagrawal123/PostgresGallery/

For this task, you will need to fix a bug in our gallery.

Currently, there are no categories for the gallery, all the items are just flat files.

For every item added to the gallery, it should be categorized.

In order to complete this task, you will need to:

1) Add category support to the gallery items. 2) The homepage will need to be reworked to show items based on categories, rather than just a flat list.

To complete this task, submit a PR that fixes this bug.
