Hi,
Thanks for contacting us here about this extension.
Filter機能はDropDownで絞り込めますか?
Userに毎回入力してもらうのは避けたいです。
At the moment, users can filter by typing into the field at the top of each column.
However, we are actively working on a feature to enable filtering by selecting parameters
from a dropdown menu or similar interface.
Cheers,
