Thrown by forty-cdk/menu.
[forty-cdk/menu] FORCDK-MENU-003: ForMenuItemIndicator must be used inside a [forMenuCheckboxItem] or [forMenuRadioItem] element.
Cause
No FOR_MENU_CHECKBOX_ITEM or FOR_MENU_RADIO_ITEM provider is visible from ForMenuItemIndicator. Angular resolves a directive's dependencies at the template's declaration site rather than where it is stamped, so a piece declared in an ng-template outside the root resolves nothing even when it renders inside it.
Fix
Move ForMenuItemIndicator inside a [forMenuCheckboxItem] or [forMenuRadioItem] element, declaring any ng-template it lives in there too.
