角路由父级和子级有效

Question

我遇到的情况是，如单击父菜单项“ technicalSettings”，它将打开空白视图和子菜单。

我正在寻找，当使用单击父菜单项时，视图不应更改。仅当单击子菜单项时，它才应该更改。

角度

const routes: Routes = [
      { path: 'dashboard', component: DashboardComponent },
      { path: 'technicalSettings',
        children: [
          { path: '', redirectTo: '', pathMatch: 'prefix' },
          {
              path:'disciplines',
              component: DisciplinesComponent
          },
          {
              path:'disciplines/:disciplineId',
              component: DisciplinesComponent
          }
      ] },
      { path: '', redirectTo: 'dashboard', pathMatch: 'full' }
    ];
