Filter to show caption field if it exists

[Jon]

Hi,

Matt kindly provided this to give a filtered list of tiddlers, the contents of which can be viewed on hover.

<$list filter=[tag[triangle]]>

<div class="hover-to-show">

  <$link/><br>

  <span class="hover-to-show-inner">

    <$transclude mode=block/>

  </span>

</div>

</$list>

How can I adapt it to show the caption field of a tiddler if it exists but the title field if it doesn't and still have the hover and link working?

Thanks

Jon

Try:

<$list filter=[tag[triangle]]>

<div class="hover-to-show">

    <$list filter="[all[current]has[caption]get[caption]] :else[<currentTiddler>]" variable=name >

     <$link><<name>></$link><br/> 

       </$list>

Perfect! Thanks a lot Mark.

Jon,

Mark refactrored you code as requested but a shorter for is if the cauurrent tiddler is valid use this;

{{{ [all[current]get[caption]] ~[<currentTiddler>] }}}

Or for plain text

<$text text={{{ [all[current]get[caption]] ~[<currentTiddler>] }}}/>
