User Story

1. As an end-user, while I filter items with a keyword, I can select or unselect items to hide them without clicking OK button

Accept Criteria

1. After filtering items, if users unselected items among filtering results, keikai can hide those unselected items.
2. When opening the filter dropdown, the filter dialog appears next to the target column rather than overlapping it.
   This behavior allows users to see the changes directly on the rows in real-time as they select or deselect items from the filter options. Since there is no need to press an OK button to apply the filter, it provides immediate feedback and improves usability.
   
3. no "ok" and "cancel" buttons, each check or uncheck action takes effect immediately on the filtering range without clicking any button.
4. provide a "clear filter" button to reset all items to the selected state and clear the search keyword.
