Position :
</mat-label>
<mat-radio-group [(ngModel)]="choisi.position">
<mat-radio-button value="AVANT">Avant</mat-radio-button>
<mat-radio-button value="A">À</mat-radio-button>
<mat-radio-button value="APRES">Après</mat-radio-button>
</mat-radio-group>
</mat-form-field>
Expected Behavior
What happens here
Actual Behavior
The syntax highlighter says the ngModel property doesn't exist on mat-radio-group :
Can't bind to 'ngModel' since it isn't a known property of 'mat-radio-group'.
1. If 'mat-radio-group' is an Angular component and it has 'ngModel' input, then verify that it is included in the '@Component.imports' of this component.
2. If 'mat-radio-group' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@Component.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@Component.schemas' of this component.ngtsc(-998002)
formulaire-amendement.component.ts(30, 18): Error occurs in the template of component FormulaireAmendementComponent.
The compilation phase triggered by ng serve fails with the same error :
X [ERROR] NG8002: Can't bind to 'ngModel' since it isn't a known property of 'mat-radio-group'.
1. If 'mat-radio-group' is an Angular component and it has 'ngModel' input, then verify that it is included in the '@Component.imports' of this component.
2. If 'mat-radio-group' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@Component.schemas' of this component to suppress this message.
