In the example below:
{{#content}}
<tr>
{{#show}}
<td>{{ID}}</td><td>{{fieldname1}}</td><td>{{fieldname2}}</td>
{{/show}}
</tr>
{{/content}}
is it also possible to show the field/keynames themselves of the content array? Thus showing "fieldname1" and "fieldname2" instead of the values in these fields/keys.
Thanks
No, Mustache.js cannot do this. You'll need to write a helper using something like Handlebars as outlined in this similar question
