Support for enums in dropdown selection control about nicegui HOT 1 CLOSED

That's an interesting idea! I fiddled around a bit and tried to support lists, dicts and enums. But it is rather complicated to get it working. And the desired behavior doesn't seem to be completely obvious. E.g. should on_change yield the selected enum item or only its value? Similarly the bound model could contain an enum item, a name or a value.

Therefore, I looked into your workaround, simplified it a bit and would leave it here as a recipe for connecting enums with choice elements like radio, select and toggle:

from enum import Enum, auto
from nicegui import ui

class Choice(Enum):
    a = auto()
    b = auto()
    c = auto()

model = type('', (), {'x': Choice.a})

ui.select([option.name for option in Choice], on_change=lambda: print(model.x, flush=True)) \
    .bind_value(model, 'x',
                forward=lambda name: Choice[name],
                backward=lambda item: item.name)

ui.run()

The on_change handler is just for showing the updated model values.
