I wants to manage content type by admin menu tab, suppose I am having a "news" content type and if I would go to put some news, then I have to go first "content" tab then "Add content option" would appear and after navigate it, it shows all content types where I would select news this is default Drupal functionality but I wants that there should be link in admin menu like news, so when I click on news it directly navigate to news content type page and there should be only news contents not all. So how to do that? Actually I am having a lot of content types that I wants to show, each content type by each admin menu tab and also shows the data particular for its.
Please tell every thing step by step.
