title: Link navigation menu to the same page by id with PHP
body: <p>I have small problem with mantaining current website of company i work for that is written in PHP. Boss wants that links in submenu of the main navigation bar lead to one page but to jump at the right place. 
  Now... i know how to do that with html/js but i dont know how to do that with php. </p>
  
  <p>Example:</p>
  
  <p>In main nav is link to team building page that has many headings in it. I need to make submenus for team building like packeges, activities, tours etc but they all need to lead to that one page just to different ID-s on it.</p>
