How to combine Textinput and Dropdown?

[balabas]

I need to input text with autocomplete, so I can create copy of Dropdown class with modification that catch "_on_message" event, but "Dropdown-builtin" class in fronted assets does not send messages on keypress. So, I need can't figure out, how to override it without changing package. Is it possible?

Hey! I think your best bet might be creating your own component. Have you tried adding a rio.Popup and putting your autocomplete options there?

Thanks for advice, but how i can create own component with custom frontend part? I can not find any instructions in documentation.
Popup could be solution if I could catch arrow keys from Textinput.

Sorry, that's not what I meant. I don't think you need to resort to custom HTML. Just create a python class, and inherit from rio.Component, like all components do.

In that class, combine a rio.TextInput with a rio.Popup. I think that should work for your use case
