A small Glass panel attached to a control, for a few related controls or a short explanation.

When to use

Quick settings, a filter panel, a short explanation of a value.

Best practices

  • Points at its control. One popover at a time; clicking outside or pressing Escape closes it.
  • Changes apply immediately, so there is no Save button.

Avoid

  • Warnings or confirmations. Use an alert.
  • A popover from a popover (R10).
  • Long forms. Use a sheet.
