See it in context
What it is
The centered row marks the current value while adjacent rows provide context. Several coordinated wheels can select compound values such as hours and minutes.
When to use it
Make the selected row clear and allow accessible incremental selection.
Know the difference
A dropdown opens a list; a wheel keeps neighboring values visible around a selection band.
Across platforms
Web
Native input and select controls use browser-provided picker UI; the exact presentation differs across browsers and devices.
iOS · iPadOS
Pickers can appear inline, as wheels, or inside a compact presentation. Choose a style that fits the amount of space and the value being selected.
Android
Use the Android or Material selector appropriate to the value. Calendar and time selection commonly have dedicated dialog presentations.
