Ramani over at Hacksphere is at it again. This time he outlines how to improve the Label/Archive pages in his post: Peek-A-Boo view of posts in Label/Archive pages . The default action when a label/category is selected is a new page with all the the posts in their entirety. This hack implements a method for readers to expand/collapse a post title after clicking a Label on the main page. Try it by clicking on a label in my 'Category Cloud'. Much easier navigation!
I feel Ramani has given good instructions, so I won't go into the specifics. I will warn you...when the widgets are expanded, they can be hard to follow. Just be slow and precise, follow his instructions, and all will go well.
Before starting, be sure to save your template. Then start editing. If you have a problem, let me know and I will try to help.
