Picker mobile tray when overwhelming
picker-mobile-tray-when-overwhelming
Mobile menu container — popover or tray. Use a tray when the option count would overwhelm a popover.
Description
On mobile, Spectrum picker menus live in a popover or a tray. Prefer a tray when the option count would overwhelm a popover, rather than forcing a large set into a cramped overlay. Small sets can stay in a popover; large catalogs need the tray pattern so choices remain scannable. Apply on mobile picker containers; do not force tray on desktop or on tiny lists that already fit.
When to use
Mobile menus with many picker options that would crowd a popover.
Not when
Desktop pickers, or small option sets that fit a compact popover.
Agent hint
On mobile, switch from popover to tray when the option count would overwhelm.
Mobile picker uses popover, or tray when the option count would overwhelm a popover.
A large option set is forced into a popover that the count would overwhelm, with no tray.
