Overview
AtCoder's contest ranking page now includes a feature that allows users to filter by their own custom groups (only when "Show Favorites Only" is enabled).
It also includes a feature to hide favorite users who did not participate in the current contest.
Creating Groups
The Manage Group button has been added to the Favorites Management Page. Clicking this button opens a modal.
You can create new groups and edit existing groups.
Only favorited users can be added to a group.
Users currently in the group will be highlighted in light green.
You can use the search function when adding users. The search is case-insensitive and displays users with a prefix match (wildcards are not supported).
After adding users to a group, click the Save button to save the group. You can then decide or edit the group name.
The group name must be a unique name that is not empty and does not overlap with other group names.
When editing an existing group, the original group name will be displayed as a placeholder. Selecting OK in this state will preserve the original group name.
You can change the order of groups by dragging the ⋮⋮ section in the group list.
Filtering
The Filtering by Group button added to the contest standings page opens a modal where you can set the filtering options.
Select filtering conditions using the checkboxes and then close the modal to automatically filter.
Statistics such as the fastest correct answerer, number of correct answers/number of submissions, etc. will also be updated to match the filtered rankings.
Selecting None as the group will disable filtering. The Clear Filtering button also disables filtering (however, Hide Unregistered User will not be disabled).
Selecting OR will display all users belonging to any of the specified groups, while selecting AND will display only users belonging to all of the specified groups.
Note
We cannot guarantee behavior during the contest.
Most functions will probably work without any problems, but when viewing the entire ranking table (including non-favorites), outdated information will be displayed for the fastest correct answer and the number of correct answers/submitted answers.
If you want this information, please reload the page rather than updating the ranking table with the "Refresh" button.
