I was hired recently by the owner of a music website to write some code which turns any archive page into a 2 column grid like the Genesis Developers list on StudioPress.com.
I was able to get the job done in less than 30 lines of code which can be very easily modified.
Here’s the first version.
And here’s a modified version which i improved afterwards that uses even less code.
You can use either the content limit or excerpt length in Genesis.
The code used to create both the examples above is significantly different than the code used to create the team members page template for Genesis.
