Section Header

A section title row with optional supporting text, trailing actions and an optional bottom separator.

Default

Title renders in an <h2> by default. Set HeadingLevel to match the document outline. Description renders in a muted paragraph below it. The description is dropped entirely when it is null or empty, so the row collapses to a single line.

Actions and Separator

The Actions slot sits at the end of the row and never shrinks, while the title column does — long titles truncate before the buttons give up space. Separator adds a bottom border and 12px of padding below the row.
Actions keep their native semantics, so a plain anchor works as well as a button. Use Class for the spacing between the header and the content it introduces.

Heading Level

Set HeadingLevel="3" for a subsection under an existing level-two heading. The appearance stays consistent while the document outline reflects its nesting.
