[elm-discuss] Re: Toward a Tree UI Component
Hey Jonathan, Thanks for the kudos, it's nice that this library is actually useful to people because I wrote it last year and it sat for a while. I know you said you solved the problem you were having, I just figured I'd share a github repository of the prototype work I was doing on a UI Tree component in case you wanted to compare it to another idea. Again, I wrote this code a year ago so I don't know if it will be useful to you, but I was able to get a functioning UI tree that I was happy with. https://github.com/tomjkidd/elm/tree/master/practice/tree-work best, Tom On Tuesday, October 18, 2016 at 5:21:41 AM UTC-4, Jonathan Fishbein wrote: > > Actually might have gotten it to work!

Actually might have gotten it to work!

[elm-discuss] Re: Toward a Tree UI Component
Hi Tom, Thank you for creating the MultiwayTreeZipper. I am attempting to wrap my head around it. My understanding of recursion and recursion on trees has always been spotty. I think I understand how to update a datum when a Forest/Tree is your elm model. However, I have been scratching my head the past couple days trying to figure out how to display the model? I am attempting to use the MuliwayTreeZipper to display comments & responses so I am hoping to have the responses be indented from the comments. Any ideas on how to accomplish that?
