This is my understanding of how the each filter is used: I think of each as "group by operand". So for each value of context it reduces the list to one tiddler with that value, from which you can then get the value of context.
If you reduce to a single field with get first, you can't group as all you have now is a list of contexts. You could then probably do something like this: [tag[Task]get[context]unique[]] On Monday, April 6, 2020 at 7:23:30 PM UTC+2, Mark S. wrote: > > This finds your unique contexts, puts them in the variable "item", and > lists them: > > <$list filter="[tag[Task]each[context]get[context]]" variable="item"> > <<item>> <br/> > </$list> > > The "each" operator removes duplicates.
