I'm actually using version 4.8.7.

I'm trying to find a solution that

1) Checks to see if there is data while typing in input field

2) Displays available data

3) Allows to enter new data 

I've tried the autocomplete and search in select options.  The autocomplete is only useful if you only have predefined options.  I believe the search in select would be good, but it just doesn't work on my application.  I copy and pasted your demo code and it remains disabled.

Please advise.  Thanks.

<Select getValue={ value => this.venueHandler(value)}>
    <SelectInput selected="Choose your option" />
    <SelectOptions search>
        <SelectOption disabled>Choose your option</SelectOption>
        <SelectOption>Option nr 1</SelectOption>
        <SelectOption>Option nr 2</SelectOption>
        <SelectOption>Option nr 3</SelectOption>
        <SelectOption>Option nr 4</SelectOption>
        <SelectOption>Option nr 5</SelectOption>
    </SelectOptions>
</Select>
