{#each options as { option, text }}

Variant Management
In the initial state or when there is no input value, neutral
is applied. After a value is entered, if the value validation succeeds, it switches to active
; if it fails, it switches to inactive
. When validating the form, inactive
is applied when validation fails. If the variant
prop is specified, the specified value is applied instead of neutral
.
