Description

  • downshift version: 6.0.5
  • node version: latest
  • npm (or yarn) version: latest

Relevant code or config Simple implementation of a Select component using useSelect hook. Behaviour is visible in your example implementation

What you did:

  • Open the Select dropdown
  • Switch back and forth with another browser tab

What happened:

The Select dropdown stays open / collapses inconsistently, meaning sometimes it stays open and sometimes is closes

Reproduction repository:

Problem description:

Inconsistent state change in useSelect when switching browser tabs

Suggested solution:

I don't think there is a clear industry standard for this behaviour. As far as I tested useCombobox does collapse on tab switch, so maybe that's will be good here too. If not too difficult, could create a prop to manipulate it.

Research direction
Investigate the useSelect hook implementation in the downshift source code (likely in src/hooks/useSelect.js). Look at how useCombobox handles tab switch (it collapses) and replicate that behavior. Consider using the document.visibilitychange event to close the dropdown when the tab loses visibility. The relevant files are in the downshift repository, specifically the useSelect hook. Also check the codesandbox for reproduction.
