Wanted to use popup across frames.
Tiles defination:

<definition name="x.y.z" path="/jsp/templates/template.jsp">  
<put name="header" value="/jsp/tiles/header.jsp"/>  
<put name="menu" value="/jsp/tiles/menu.jsp"/>  
</definition>  

<definition name="l.m" extends="x.y.z">  
<put name="title" value="title"/>  
<put name="header" value="/jsp/tiles/header.jsp"/>
 <put name="menu" value="/jsp/tiles/menu.jsp"/>  
<put name="lframe" value="/jsp/leftframe.jsp"/>  
<put name="rframe" value="/jsp/rframe.jsp"/>  
</definition> 

<frameset rows="8%,7%,*" cols="*" framespacing="0">
        <html:frame marginheight="0" marginwidth="0" page="<%=headerJsp%>" frameName="header" title="Header"  scrolling="no" frameborder="no" noresize="true"/> 
                <html:frame marginheight="0" marginwidth="0" page="<%=menuJsp%>" frameName="menu" title="Menu"  scrolling="no" frameborder="no" noresize="true"/> 
                <frameset cols="35%,*" framespacing="0" frameborder="yes">
                        <html:frame page="<%=leftFrameJsp%>" frameName="frLeft" styleId="frLeft" title="Tree"  scrolling="auto" marginheight="0" marginwidth="0"/> 
                        <html:frame  page="<%=rightFrameJsp%>" frameName="frRight" styleId="frRight" title="Body"  scrolling="auto" marginheight="0" marginwidth="0" /> 
                </frameset>        
</frameset>

Inside leftframe.jsp

i am having the

<div id="popup" style="display: none;"></div>
<div id="window" style="display: none;">
Some Content. 
</div>

And the script to show and close popup

is

function Show_Popup() {	
                $('#popup').fadeIn('fast');	
                $('#window').fadeIn('fast'); 
        } 
        function Close_Popup() { 
                $('#popup').fadeOut('fast'); 
                $('#window').fadeOut('fast'); 
                
        }

1st--How will i get the popup at the center(It is comming over left frame and fading in the leftframe only If i drag it also the lframe only getting expanded with scroll a bar within the leftframe.)
2nd--How can i fade in/fade out all the frame and get the pop up at the center and chould be draggable anywhere not for only the frame from which initiated.
