You might need to update to the latest version, it looks like that line in components.py that is giving the error changed in this commit https://github.com/AnswerDotAI/fasthtml/commit/170fb7ec3b03e7c2411dbcdf67151d8b9d101121#diff-9c7f3d7dc5f2f135e875dcfaff1efd7e64e94366d47e53f1a6890eed0934cfe1 .

You can see here it currently reads tag,c,kw = ft(tag, *c, attrmap=attrmap, valmap=valmap, **kwargs).list . I think the missing .list is what causes your error probably.

tl;dr does it work if you update to the latest version of fasthtml?
