is there a way to get bootstrap's typeahead to only match the first characters of a word? Right now it's matching *any* instance of the entered characters anywhere in each word, and I only want it to match the beginning.

For instance, if my array is

PHP Code:
array("roof company""company de roofing""experts in roofing"
and I type in "roof" I only want "roof company" to appear.

Does this make sense?
