Modifying this code and adding some javascript to my WordPress site, I was able to create a nifty grid formatted list of posts that could be filtered (by tags) using a dropdown box.

You write awesome code. Thank you!
Here's the link to my javascript

Hi @jer0dh. Is there a way to add alphabet numbers between posts that are being ordered?
My page is almost done, just need the alphabet numbers between the different ordering:

You will see there is an example below the first section, but this currently only uses tags.
