on index.php sidebar shows news. in navbar if click i.e useful links sidebar should alter showing news showing couple of links.

and if possible, if click on 1 of links should alter content under navbar , sidebar should still show useful links.

<?php include('include/header.php'); include('include/nav.php'); ?> <div class=content> <h1>heading 1</h1> <p>text goes here</p> </div> <?php include('include/nyheter.php') ?> <--not part of code! sidebar <?php include('include/footer.php')
