All metadata options should be covered using the built-in support. However, there may be custom metadata tags specific to your site, or brand new metadata tags just released. You can use the other option to render any custom metadata tag.
layout.js / page.js export const metadata = {
  other: {
    custom: 'meta',
  },
}
<head> output <meta name="custom" content="meta" />
Unsupported Metadata
The following metadata types do not currently have built-in support. However, they can still be rendered in the layout or page itself.
