By default subheadings are disabled for posts, you can enable them on the settings page Plugins > SubHeading > Enable for posts as well as pages.

What custom field name does it use?

The field name used is _subheading, the underscore prefix prevents it from being displayed in the list of custom fields.

How can I append the subheading to my RSS feed?

Check the RSS option on the settings page Plugins > SubHeading > Append to RSS feeds.

What if I want to include shortcodes in my subheading?

Check the apply shortcode filters option on the settings page Plugins > SubHeading > Apply shortcode filters.

This will apply any existing shortcode filters to the subheading value you have set.

How can I prevent the subheading input moving to the top of the edit page?

Some plugins will hide the element containing the post title, which is this element that the subheading input is appended to.

You can prevent the repositioning of the input via the options page.

What are the `Before` and `After` inputs used for?

If you are using the Automatically append before the content option, you can include custom content before and after the subheading is displayed.

For example, setting Before to <h3> and after to </h3> will wrap the subheading in a h3 tag.
