I just searched "huffingtonpost" on google and saw the result which is a well built even featuring search bar. Please check it here or search yourself. http://www.google.com/#hl=en&q=huff...8g1g-c1&aql=&oq=&gs_rfai=&fp=95b5ca8630a93ba4 How do you do your sitemap to come out like that?
Here are 4 simple steps to get it done : 1. Enter your full website URL and some optional parameters in the form below 2. Press 'Start' button and wait until the site is completely crawled (the progress will be indicated) 3. You will see the generated sitemap details page, including number of pages, broken links list, XML file content and link to a compressed sitemap. Download the sitemap file using this link and put it into the "public_html/" folder of your site. 4. Go to your Google Webmaster account and add your sitemap URL. Please check About Sitemaps for more details.
I think you are referring to the sitelinks appearing under the search result. You can see and remove your sitelinks in Webmaster Tools under Site configuration\Sitelinks. You cannot add sitelinks, they are automatically created by Google for your site.
