Query regarding Dojo Type Ahead component(FilteringSelect)

[Lax]

Hi,
 
Dojo's Type ahead component (FilteringSelect) defaults behavior is, as user typing in text it auto populates the very first item in the dropdown list into the text box. Is there any way to switch off this auto population by changing configuration on the FilteringSelect component?
 
Only way I could do is by modifying the dojo source code. Just wanted to know if there is any better solution available.
 
Thanks In Advance,
Lax
