FORCDK-SELECT-004
Thrown by forty-cdk/select.
[forty-cdk/select] FORCDK-SELECT-004: ForSelectIndicator must be used inside a [forSelectOption] element.
Cause
No FOR_SELECT_OPTION provider is visible from ForSelectIndicator. 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 ForSelectIndicator inside a [forSelectOption] element, declaring any ng-template it lives in there too.
