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.Link Action
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.
