multiTV wrapper:
<span class="hide">[+wrapper+]</span>

multiTV row:
-

Notes:

a This requires Jako's phx outer snippet
<?php
/*
* description: surround not empty string with text
* usage: [+string:outer=`before|after`+]
*/

$options = explode("|", $options);
if (count($options) == 1) {
    $options[1] = '';
}
if (trim($output) != '') {
    return $options[0].$output.$options[1];
} else {
    return '';
}
;
?>

b I setup a css class called hide with display:none to hide the multiTV row output ( the dashes '-' )

multiTV call:
[!multiTV?
&tvName=`files`
&docid=`[*id*]`
&outerTpl=`pdfs-wrapper`
&rowTpl=`pdfs-row`
!]

multiTV wrapper:
<a name="anchorTech"></a>
<h2>PDFs</h2>
<ul>
[+wrapper+]
</ul>

multiTV row:
<li><a href="[+pdf+]" title="[+title+]" target="blank">[+title+]</a></li>

[*phx:multitvisempty=`files`:then=``:else=`{{button-PDF}}`*]

(this should also work in the opposite: [*phx:multitvisnotempty=`files`:then=`{{button-PDF}}`:else=``*] )

Notes:

a This requires Jako's 2 custom phx modifiers (multitvisempty.phx.php and multitvisnotempty.phx.php)
