David Nicholson has devised another great way to add categories to your Blogger blog. There are two template edits required. One new code string goes in each post that you want to categorise. You make a minor edit each time to make the code contain the category that you want. Use Blogger's Post Template to keep the code handy, then all you need to do is add the category. David offers two versions of this post-tagging script. The first tags the posts without showing the tags, by displaying a transparent single-pixel image. The second has some display customisation options, and will show the selected category on the post.

To display your categories, David has whipped up a spiffy ajax sidebar menu with a dancing-cube widget (looks very slick) & all you need to do is add the code to your sidebar where you want the list to appear. Very cool! The list of posts in a category also includes a "display all categories" link to reload the top-level menu.

Amit at NerdierThanThou has offered a couple of upgrade suggestions, one of which seems to have been implemented already. David is not requiring an account or signups, and has a great "how this works" section in his post that walks the reader through the process. Good stuff!!
