Restrict input to items available in dropdown

[ksultana]

Hi,

This is not an issue really, just to see if this feature is available. Bdw great work!

I'd like the user to input text from what is available in the dropdown. Anything else would be removed. Would this be possible please? So, say I start typing and what I type isn't available in the dropdown.. could I have the text removed from the input automatically?

Thanks,

@vlazar, I think we've received this request often enough that we need to support this by default somehow (perhaps if you link to a <select> this is what happens?).
In the meantime, we should have an advanced example for how to do it right now.
