List has where filter function?

[xietuhuo]

I want to customized my special list (like marker with sym.triangle.filled),but when I use show list.where(marker:blabla) :set rule ,it has no effect. can't List have the more detailed management.

The filter is a bit weird, as you have to wrap the marker in a content block. This works:

#show list.where(marker: [#sym.triangle.filled]): set text(red)

#list(marker: sym.triangle.filled,
  [This is red],
  [and so is this]
)

- But this is not

However, if you set the marker to an array, you can't filter out list items that use a specific marker.

Three level list is necessary for me. So I customize my favorite marker with array set . I see. TKS.
