It can be hard to understand what is in a key value field. The below code will loop over the values and spit out the keys and the values.
#if ($UtilMethods.isSet($content.metaData)) <h2>Metadata</h2> <table class="metadata"> #foreach($key in $content.metaData.entrySet()) #if($key.key != "map") <tr> <td>$key.key</td> <td>$key.value</td> </tr> #end #end </table> #end
