Not now, that I'm aware of. But with Bloc, this will be possible (Pharo 6 maybe)? Meanwhile, a Summer of Code proposal [1] tries to create a better user experience (UX) with emphasis on the markdown markup writing experience. Stay tuned :-).

Re: [Pharo-users] How childrenBlock: in TreeModel works

by Peter Uhnak

I guess something like this could work... ``` d := { Dictionary with: #n -> 'whatever' with: #d -> { Dictionary with: #a -> #AA with: #b -> #BB. Dictionary with: #c -> #CC with: #d -> #DD }. Dictionary with: #n -> 'wherever' with: #d -> { Dictionary with: #a -> #AA with: #b -> #BB. Dictionary with: #c -> #CC with: #d -> #DD }. }. TreeModel new roots: d; childrenBlock: [ :item | item isDictionary ifTrue: [ item associations flatCollect: [ :pair | pair value isArray ifTrue: [ pair value ] ifFalse: [ {pair} ]. ] ] ifFalse: [ #() ] ]; openWithSpec ``` but forcing this much behavior is a bad practice... because it's hard to read, hard to understand, and hard to test. So I suggest using custom classes as nodes (so each node can simply tell what its children are), and then delegate the retrieval... you could also add extension methods to the respective classes' protocols to acheive the same...
