Description

Environment

  • Package version(s): v3.38
  • Operating System: Linux/Windows
  • Browser name and version: Google Chrome v88

Code Sandbox

https://codesandbox.io/s/blueprint-sandbox-forked-j4ooz?file=/src/index.tsx

Steps to reproduce

ezgif-3-4c479ecd4a65

  1. Select (Past month) shortcut
  2. Select any of the smaller ranges shortcut from shortcut menu (Past week, Yesterday, Today)
  3. The selected range will not appear in the single month shown

Actual behavior

Selected range is inconsistent after toggling from past month to current week/day ranges from shortcut menu in single-month mode only.

Expected behavior

The calendar should show the month where the currently selected range is, instead of the previous one.

Possible solution

Not sure about the solution. Switching from past 3 month to current week/day works fine. Showing ending month as default may not also not be a correct solution as for higher ranges(6month,1 year), it will show the current month.

Research direction
Investigate the DateRangePicker component, specifically the logic for selecting shortcuts when singleMonthOnly is enabled. The issue suggests that switching from a past month shortcut to a current week/day shortcut does not update the displayed month correctly. Look at the shortcut selection handler and month navigation logic in the source file (likely src/components/date range picker/). Check if there is an existing fix or related PR mentioned in comments.
