Context Menu Target

Portable context-menu actions for module faces and controls on Base UI's ContextMenu (right-click and touch long-press) and the ContextMenu key or Shift+F10, plus ActionMenu: the same menu opened from a button, the ellipsis in a card header. Both run on one Base UI Menu engine and one row renderer (check column, label, a right-aligned hint such as a shortcut or a size, submenu arrow, optional separators, and non-interactive readout rows for a figure such as a code size). Fields keep the browser's own menu. Both portal into the fullscreen element while a face is in browser fullscreen and stack at the --uikit-z-overlay token.
