Defined in:
app/components/phlex_kit/field/field_error.rb

Overview

Validation message(s) for a Field, ported from shadcn/ui's FieldError. Pass errors: an array of message strings (deduped; one renders plain, several render a list) or give a block. Renders nothing when empty — matching theirs. Distinct from FormFieldError, which is the Stimulus live-validation slot; server-rendered errors belong here. See field.rb.
