Disable Highlighting in Picker List

Hi ,

I am facing a issue while using picker list in smartClient. My picker list is working as usual but i want to customize something for my work.

a) Its highlighting first item by default in case it doesn't find any matching word in picker list.

For e.g.
If i type "abc" in my search box , its displaying results in picker list like " abcd , abcr, abct, abcrg" and its highlighting the first result i.e. "abcd". As there is not exact match for word "abc".

I want to disable the highlighting in case if it doesn't find any exact matching word.
