Low Variables Magic - Nesting, Preparsing, Var Types, etc

low-variables-magic

First I'm using the Low Variables Single tag to pull in a Textarea var type for the country-specific header, 
using the preparse: paramter to pass the {lang} and {segment_1} vars...

   <div id="header">
      {exp:low_variables:single var="lv_header_{lang}" preparse:lang="{lang}" preparse:segment_1="{segment_1}"}
   </div>

Then inside the above {lv_header_{lang}} var, I have the country-specific logo, contact info, nav menu, etc.
For the nav menu, I'm using a Low Variables Pair tag to output a nested Playa var type...

   <ul>
      {exp:low_variables:pair var="lv_main_menu_{lang}"}
         <li>
            <a href="#"><h3>{cf_page_heading_{lang}}</h3></a>
            <ul>
               {exp:playa:children field="cf_page_subpage_listing_{lang}"}
                  <li><a href="/{lang}/{segment_1}/{url_title}">{cf_page_heading_{lang}}</a></li>
               {/exp:playa:children}
            </ul>
         </li>
      {/exp:low_variables:pair}
   </ul>
