Saq,
Is the demand for a single filter expression a needed constraint?, because
a filtered transclusion can be used to display the caption or title? Or am
I missing something?
<$list filter="[tag[Widgets]]">
<$link><$text text={{{ [all[current]get[caption]else[{!!title}]]
}}}/></$link><br>
</$list>
Whilst we can squeeze more out of filters it is easy to overloads them, In
my above list the list filter relates to the selection the filtered
transclusion to the display of the item. They are distinct functions and
need not be combined.
Regards
Tones
