I bit more work for these rare cases, but this keeps the language syntax easy. default might be autohide=all. Let me know if you have situations where you need more control, we'll take a look. Here is an example. I threw in the {{altsection}} tag just to spur some discussion :-) <TABLE> <TR> {{section sec1 autohide=all}} <TD>Category: {{ $category }}</TD> {{section sec2 autohide=any}} {{* this section hides if headline OR date are emtpy *}} <TD> Article: {{ $article_headline }} Date: {{ $article_date }} </TD> {{altsection}} {{* this displays if sec2 was hidden *}} <TD> No articles to show </TD> {{/section}} {{/section sec1}} </TR> </TABLE>
