Saq,
Could you give some idea of how/why* It is going to be used in a context
where other wikitext cannot be introduced. ?*
- Do you want it in a "filtered transclusion"? see below
Of course the following does what you want but the currentTiddler is not
available inside the list.
<$list filter="[tag[Widgets]sort[title]] +[get[caption]else{!!title}]">
</$list>
This also achieves the same?
In the template you have access to the current tiddler, in the same way as
my first response with an inline template?
<$list filter="[tag[Widgets]sort[title]]" template="caption-or-title">
</$list>
Where caption-or-title contains
{{{ [all[current]get[caption]else{!!title}] }}}<br>
*In a filtered transclusion you can use a template*
{{{ [tag[Widgets]sort[title]]||caption-or-title}}}
I am interested in the challenge.
Regards
Tones
