Subhead should support multiple use

[chrisvanpatten]

Subheads currently have supports.multiple = false but I believe this should be true.

The main use-case would be an article or page with multiple sections, which need a subhead for each section of content.

This has a PR now, #8143, for those with labeling powers :)

No it was added as a single use block under the title #2091

Do we really need this Block? It is a paragraph with a class. I don't think many people, including me, really understand when to use this block.

@Soean I know it was made single use when it was originally added, I'm just saying maybe it should be multi-use so it can be used in content with multiple sections.

But in that case I also think removing it and make it a block style on the paragraph block would be fine.

Is that a Needs Design Feedback question?

(Also fwiw I think the idea of the subhead is much more common/understood by folks in journalism/newsrooms.)

Added the Needs Design Feedback label to see about getting an answer to @Soean's question about whether the subheading block is really needed. If it is kept, what is its intended use case and what makes a subheading different than using a smaller heading such as h3, h4, h5, or h6?

[chrisvanpatten]

the subhead (also known as subheader, standfirst, rider, kicker, bankhead) in journalism is an introductory or summary line or brief paragraph, located immediately below the headline, and typographically distinct from the body of the article

Whether it should be an h-tag or a paragraph is up to interpretation, although I'm of the opinion that a <p> is more correct, semantically. Headings/h-tags should be used to denote the title of a given section or sub-section, whereas the subhead supports and provides context for a heading. You'd really never have a subhead without a heading.

Another way to think about it: if you were generating a table of contents from H-tags (as we do in the Document Outline popover), you wouldn't want the subheads in there, therefore they are more appropriate as <p> tags.

[chrisvanpatten]

Just for the sake of clarity, here are our options (I think):

• Keep the subhead block, making it multiple use to support using it when a page has multiple sections
• Keep the subhead block, but leave it as a single use
• Remove the subhead block, and add "Subhead" as a Block Style on the Paragraph block
• Remove the subhead block, without adding it as a Block Style

[karmatosed]

Let's keep it for now as a single use. I have seen it used by people so for now keeping it makes sense. We can always revisit this decision.
