OptionalbadgeOptional count badge rendered at the right of the item.
OptionalchildrenOptional child items for tree-structured nav (e.g. Testing Explorer's
Test Suites tree). When children is undefined the item renders as a
plain flat-list item (existing behavior). When defined — even as an empty
array — the item participates in tree rendering: a chevron toggle shows
for non-empty arrays, and an equal-width placeholder reserves alignment
space for leaves so siblings line up. Expansion state is owned by the
consumer via [ExpandedIds] on <mj-left-nav>.
OptionaldescriptionOptional muted secondary line shown under the label.
OptionaldisabledWhen true, the item renders dimmed and is not clickable.
OptionaliconOptional Font Awesome icon class (e.g. 'fa-solid fa-users').
Stable identifier — used for active-state matching and emitted on click.
Primary label rendered as the item's main text.
A single item in an
<mj-left-nav>.
