Subject Aw: Re: Re: ListItem and enclosure problem
Date Thu, 08 Jun 2017 10:23:44 GMT
But wouldn't this only hide the complete listview when there is no item?
I want to remove markup only for an empty item.

So something like
<ul>
  <li id="foo:0"><span id="bar">1</span></li>
  <li id="foo:1"><span id="bar">2</span></li>
  <li id="foo:2"><span id="bar">3</span></li>
</ul>

should become in case foo:1:bar is invisible

<ul>
  <li id="foo:0"><span id="bar">1</span></li>
  <li id="foo:2"><span id="bar">3</span></li>
</ul>

Thank you
Per
