I have also done that successfully by setting up a namespace and defining
default macros that can be overridden. 

What I have done is basically this: 


#############
# layout.ftl
#############

<#macro heading>
	DEFAULT HEADING
</#macro>

<#macro content>
	DEFAULT CONTENT
</#macro>

<#macro leftNav>
	DEFAULT LEFT NAV
</#macro>


<#macro doLayout>
    <html>
        <body>
        	<div id="head"><@heading /></div>
        	<div id="leftNav"><@leftNav /></div>
        	<div id="content"><@content /></div>
        </body>
    </html>
</#macro>

#############
# END layout.ftl
#############




#############
# page.ftl
#############
<#import "layout.ftl" as layout />


<#macro heading>
	MY IMPLEMENTATION OF THE HEADING
</#macro>
<#assign heading = heading in layout /><#-- THIS PUSHES THE heading MACRO
INTO THE layout NAMESPACE (OVERRIDING THE ORIGINAL heading MACRO) -->


<#macro content>
	MY IMPLEMENTATION OF THE CONTENT
</#macro>
<#assign content = content in layout /><#-- THIS PUSHES THE content MACRO
INTO THE layout NAMESPACE (OVERRIDING THE ORIGINAL content MACRO) -->


<#-- NOW, CALL THE LAYOUT - the default leftNav is used, but this page
overrides the content and heading sections -->
<@layout.doLayout />

#############
# END page.ftl
#############

guide Tony ! 
 Actually i have thought of using the loop variable param,  but i wonder
how to provide the default section content, since what i intended is to
override some sections as needed, and use the default sections if not
'overriden' 
 Example : for page1.ftl, i want to supply the body only, but use the
default left-panel, default header n default footer for page2.ftl, i want
to supply both the body and left-panel, and still use the default header n
default footer

 Sorry about that previous post! I accidentally sent the email, I just
love
 coding in a bad browser based email client!

 What I have done in the past is this:

 Write your header section here.

 Write your content section here.

 Unsupported section??
