title: Django: Figure out which item in a menu that has been selected
body: <p>I'm sure I've seen this question on Stack Overflow before, but I couldn't find it by my life, so here goes nothing.</p>
  
  <p>I have a normal Django menu which uses the <code>{% url %}</code> tag and static names for the menu items. Now I want to have a different style for the menu item which has been selected. But the menu is being rendered in the base template, so how do I figure out which menu item it is?</p>
