[BUG]fix suggestion list cutoff issue

In this PR, we fixed the suggestion list cutoff in an easy way.
We replace 250px width to auto min-width to allow browser to
select a width for specific element.

However, we might have longer input that can't fit into the search.
We definitely need more feedbacks on the cutoff behavior.

#2555
