For some reason I could make my OP with an attachment, so here is the code
from the tid file. Just create a tiddler and copy it in.
\define showAncestors()
<$list filter="[enlist<mylist>first[]]">
<ul><li>
<$list
filter="[<currentTiddler>!match<bottom-tiddler>then<currentTiddler>]">
<$list filter="[<currentTiddler>has[parent]then{!!text}else{!!title}]">
<<currentTiddler>>
</$list>
</$list>
<$list filter="[<currentTiddler>match<bottom-tiddler>]">
<$vars
question={{{ [{!!text}splitbefore[::]addprefix['']addsuffix['']] }}}>
<<question>>
</$vars>
</$list>
<$set name="mylist" filter="[enlist<mylist>rest[1]]">
<<showAncestors>>
</$set>
</li></ul>
</$list>
\end
\define getAncestors()
<$list filter="[all[current]get[parent]!is[blank]]" emptyMessage="""<$set
name="mylist"
filter="[enlist<mylist>reverse[]]"><<showAncestors>></$set>""">
<$set name="mylist" filter="[enlist<mylist>] [<currentTiddler>]">
<<getAncestors>>
</$set>
</$list>
\end
\define thing()
<$set name="mylist" filter="[<currentTiddler>]">
<$vars bottom-tiddler=<<currentTiddler>> >
<<getAncestors>>
</$vars>
</$set>
\end
<$list filter="[search:text[::]!is[system]!<currentTiddler>]">
<$macrocall $name=rememberq id={{!!created}}
question=<<thing>>
answer={{{ [<currentTiddler>get[text]split[::]last[]] }}}
/>
</$list>
