Jean-Pierre;
I am not sure about your requirement, but try these
<$list filter="[enlist[a1^a2 b1^b2 c1^c2]]">
{{{ [<currentTiddler>split[^]first[]] }}}
</$list>
<hr>
<$list filter="[enlist[a1^a2 b1^b2 c1^c2]]">
<$list filter="[<currentTiddler>split[^]first[]]">
</$list>
</$list>
<hr>
<$list filter="[enlist[a1^a2 b1^b2 c1^c3]split[^]]">
</$list>
<hr>
<$list filter="[[a1^a2 b1^b2 c1^c3]split[ ]split[^]]">
</$list>
I was recently considering a similar problem, when someone was questioning
nesting list widgets, when I realised the $list with filters can act as
gosub, while, do until etc... so nesting them is by definition sometimes a
logical requirement depending what you are trying to achieve with your
filters. Nesting is not easy or possible in many cases with triple curly
braces.
