How to have panels constant throughout the application

[bweliky]

I have a page where I have three panels...left panel,center panel,right panel...My question is this...I have a link in my center panel and that link takes to another page...But I want the new page to be displayed in the center panel with the condition that left and right panel should remain as such...I am able to display the 2nd page in center panel but I am not able to hold back the left and right panel...My code:\[code\]<div id="wrapper"> <div id="centerPanel"> center panel <a href="http://stackoverflow.com/questions/15810160/<s:url action="ViewAppeals"/>">View Appeals</a> </div></div><div id="leftPanel"> leftpanel</div><div id="rightPanel"> rightpanel</div>\[/code\]
