[TYPO3] Show menu title (current page) only if the MENU has been filled (is not empty)

[Karol Martinka]

Hello,

I have this code :

20 = HMENU
 20.special = directory
 20.stdWrap.dataWrap = <h2>{page : title}</h2><ul>|</ul>
 20.1 = TMENU
  20.1.NO {
  allWrap = <li>|</li>
 }

I would like to show the dataWrap only if the menu has entries.. That means, 
I need a menu with header, which will be displayed, only if the menu has 
entries.. I think there should be more ways how to achieve it, but I'm 
playing with it for about 2 hours without success.

Btw. how is the IF in HMENU working?!

Thanks,
Karol
