Вы можете использовать ndc-dynamic
пакет, это мой способ реализации
HTML
<gridster id="dashboard" #dashboard [options]="options" (drop)="onDrop($event)" class="transparent">
<gridster-item #gridsterItem[item]="item" *ngFor="let item of dashboardArray">
<ndc-dynamic class="no-drag" [ndcDynamicComponent]="item.component" [ndcDynamicInputs]="item.input"
></ndc-dynamic>
</gridster-item>
</gridster>
TS
onDrop
событие
this.dashboardArray.push({
rows: 4,
cols: 4,
x: 0,
y: 0,
componentType: DashboardComponentType.Grid,
input: {
chartId: '',
dashboardId: this.dashboardId,
},
component: GridChartComponent,
name: "GridChart"
})
