[Prift2004]

I have this menu:\[code\]<ul class="semiopaquemenu"> <li><a href="http://www.artoparadosikilkis.gr/home/">home</a></li> <li><a href="http://www.artoparadosikilkis.gr/proionta/">products</a></li> <li><a href="http://www.artoparadosikilkis.gr/paraggeleies/">orders</a></li> <li><a href="http://www.artoparadosikilkis.gr/location/"class="selected">location</a></li> <li><a href="http://www.artoparadosikilkis.gr/about-us/">about-us</a></li> <li><a href="http://www.artoparadosikilkis.gr/contact-us/">contact</a></li></ul>\[/code\]This is a horizontal menu that is highlighted on mouse over and the current page is highlighted also on clickmy question is how can I modify my code so I can put it only one time.the example highlights the location tab and the code is on the location page what I want is something like \[code\]<ul class="semiopaquemenu"> <li><a href="http://www.artoparadosikilkis.gr/home/"if selected=true then class="selected">home</a></li> <li><a href="http://www.artoparadosikilkis.gr/proionta/"if selected=true then class="selected">products</a></li> <li><a href="http://www.artoparadosikilkis.gr/paraggeleies/"if selected=true then class="selected">orders</a></li> <li><a href="http://www.artoparadosikilkis.gr/location/"if selected=true then class="selected">location</a></li> <li><a href="http://www.artoparadosikilkis.gr/about-us/"if selected=true then class="selected">about-us</a></li> <li><a href="http://www.artoparadosikilkis.gr/contact-us/"if selected=true then class="selected">contact</a></li></ul>\[/code\]
