Picker readonly only if selection
picker-readonly-only-if-selection
Read-only only if a selection exists — a picker with no selection has no read-only option.
Description
Spectrum allows read-only on a picker only when a selection already exists. An empty picker has no read-only option, because there is no value to preserve. Use read-only when the chosen value must stay visible and non-editable; leave unset pickers interactive or omit the control rather than marking them read-only. Do not confuse this with disabled unavailable fields that are out of play entirely.
When to use
Showing a locked picker value that must remain visible after choice.
Not when
Empty unset pickers, or disabled unavailable fields with no value to keep.
Agent hint
Make a picker read-only only after it has a selection; never empty read-only.
Read-only picker has a selection. Empty picker is not read-only.
Read-only picker with no selection.
