Your blog have a lot of categories or labels ? You want to display the post on the label in the form of a feed? You can combine RSS feeds with the label on your blog, for make it also easy. Just use your Feed url for show your label content in feed mode.

You can use the Feed label URL in your RSS widget.

If you confused with my explanation, look this URL below :

http://www.bloggercustom.net/feeds/posts/default/-/Blogspot Tutorial

Notes ! If have a space ex : Blogspot tutorial, change the space with %20. So, the result is Blogspot%20Tutorial.

The link is combined the primary URL feed ( http://www.bloggercustom.net/feeds/posts/default )with your label url with strike ( - ). Then, after the strike code is the label name. ( http://..../-/label name). Edit with your own label.

You can also create in widget. For example like "recent post" but with more specific content, your label. This step is how to make it :
1. Create new element. Choose RSS feed widget.

2. In new Window, fill the blank place with your Feed. Then click next.
For ex : http://www.bloggercustom.net/feeds/posts/default/-/Blogspot%20Tutorial

3. Finish. Now you hava a Recent Blogspot tutorial widget :D.

Attention!

I have try it in comment URL ( http://www.bloggercustom.net/feeds/comments/default/-/Blogspot Tutorial ) is does not work properly. I do not know where the location of the error, whether in the Feed URL or other factors. I have not try it with blogspot domain, maybe I use custom domain in my blog.
