Form component. If errors are present, renders a
<div> element around a banner message and around an unnumbered list of
error messages. Renders nothing if the ValidationTracker shows no
errors.Form| Name | Type | Flags | Default | Default Prefix |
|---|---|---|---|---|
| banner | String | message: | prop | |
| The banner message displayed above the errors. The default value is "You must correct the following errors before you may continue.". | ||||
| class | String | symbol: | literal | |
| The CSS class for the div element rendered by the component. | ||||
