How can I make a drop down box showing all the posts in a category? so for example if I'm viewing a post that under the Banana category then I want it show a drop down box listing all posts in Banana category.
Dagon Design makes a good plugin that does this for you. http://www.dagondesign.com/articles/drop-down-post-list-plugin-for-wordpress/ Easy set up and will show posts from a specified category
