HyMenu

A role="menu" panel composed on top of hy-popover. Owns keyboard navigation (Arrow, Home/End, typeahead), roving tabindex, and submenu coordination. Items are slotted in the default slot and may be grouped with hy-menu-group or separated with hy-divider.

Trigger patterns

By id — pass for="<id>" referencing the trigger. Requires a manual click handler on the trigger to call menu.toggle().

Programmatic — call menu.show(anchor?) with an optional element. When an element is passed, the menu anchors to it (generating an id if the element doesn't already have one).

Composite triggers — hy-menu-button, hy-context-menu, and hy-menubar-item wrap hy-menu and handle trigger wiring themselves.

Events

• select - { value, item, originalEvent } — bubbled up when any child item fires select.
• show - { source } — forwarded from the underlying popover (does NOT bubble).
• hide - { source } — forwarded from the underlying popover (does NOT bubble).
• request-show - { source } — cancelable, forwarded from popover.
• request-hide - { source } — cancelable, forwarded from popover.

Slots

• default - Menu items (hy-menu-item, checkbox/radio variants, groups, dividers).

Methods
