Daniel Dekany commented on FREEMARKER-25:
-----------------------------------------
This is one of the most wanted missing features (well, variations of this), but
was never implemented. Something that you can do to work this around is
introducing a {{TemplateDirectiveModel}} that captures its output and then puts
it into a custom {{Map}} attribute in the {{Environment}} with a given key
(like "{{HEADER"}} in your case). Then, with another
{{TemplateDirectoveModel}}, to which you specify the same key ({{"HEADER"}})
you print the captured content to the output. If you know FreeMarker enough, I
think the end result can look very close to a core feature. Like you can
capture with {{<@def.header>...</@>}}, then print with {{<@printDef.header
/>}}. And, the enclosing macro ({{MY_TABLE}}) needs to set up the scope which
created a clean {{Map}} in the {{Environment}}, like
{{<@collectDefs>...<#nested>...<@printDef.header ...>...</@collectDefs>}}.
Something like that. But of course it should be a core feature. I think I will
try to prototype this using custom directives when I find the time.

> Key: FREEMARKER-25
> URL: https://issues.apache.org/jira/browse/FREEMARKER-25
> Project: Apache Freemarker
> Issue Type: Wish
> Components: engine
> Affects Versions: 2.3.24
> Reporter: Charles Goodwin
>
> We spend a lot of time getting around the inability to have multiple nest
> targets in our freemarker usage.
> For example, defining a table with a custom column header/cells.
> The desired feature would work something like:
> {noformat}
> <#macro MY_TABLE>
> <table>
> <head>
> <column A/>
> <column B/>
> <#nested HEADER>
> </head>
> <body>
> <rowtemplate>
> <celldef A/>
> <celldef B/>
> <#nested>
> </rowtemplate>
> </body>
> </table>
> </#macro>
> {noformat}
> With the end usage being:
> {noformat}
> <@MY_TABLE>
> <@:HEADER>
> <column C/>
> </@:HEADER>
>
> <celldef C/>
> </@MY_TABLE>
> {noformat}
