Moore Dropdown Archives is the sister plugin to Moore Dropdown Categories. The plugin creates a simple and valid XHTML dropdown menu that automatically submits when the month is selected from the dropdown. I can’t take full credit for the code that my plugin contains. Actually, I can’t take any credit. The code was originally written by Chris at qwghlm.co.uk and I simply wrapped it up as a plugin so that no hacking of the WordPress core is necessary.
