Thanks Stanislav .I have couple of more queries
1) I need to add a search for all listed newsitems ,So I added Search box and search result box but even after creating search Indexes only on newsitems ,it seems to search the entire site.
2) I have been trying to create a custom news search box result template which display results same as in newsItems list and copied news list template to search result template but its not working.
3) How do I set page url for News Archive link 2015 ,"company->news->2015"? Clicking on 2015 should open up a new page http://localhost/news/newsArchive but its opening on the same page I have this navigation widget which is http://localhost/news
