Example

As we re going to use a Tab, We ve to update app.module.ts used in ngx-bootstrap Sortable chapter to use TabsModule and TabsetConfig.

Update app.module.ts to use the TabsModule and TabsetConfig.

app.module.ts

import { BrowserModule } from  @angular/platform-browser ;
import { NgModule } from  @angular/core ;
import { BrowserAnimationsModule } from  @angular/platform-browser/animations ;
import { AppComponent } from  ./app.component ;
import { TestComponent } from  ./test/test.component ;
import { AccordionModule } from  ngx-bootstrap/accordion ;
import { AlertModule,AlertConfig } from  ngx-bootstrap/alert ;
import { ButtonsModule } from  ngx-bootstrap/buttons ;
import { FormsModule } from  @angular/forms ;
import { CarouselModule } from  ngx-bootstrap/carousel ;
import { CollapseModule } from  ngx-bootstrap/collapse ;
import { BsDatepickerModule, BsDatepickerConfig } from  ngx-bootstrap/datepicker ;
import { BsDropdownModule,BsDropdownConfig } from  ngx-bootstrap/dropdown ;
import { PaginationModule,PaginationConfig } from  ngx-bootstrap/pagination ;
import { PopoverModule, PopoverConfig } from  ngx-bootstrap/popover ;
import { ProgressbarModule,ProgressbarConfig } from  ngx-bootstrap/progressbar ;
import { RatingModule, RatingConfig } from  ngx-bootstrap/rating ;
import { SortableModule, DraggableItemService } from  ngx-bootstrap/sortable ;
import { TabsModule, TabsetConfig } from  ngx-bootstrap/tabs ;

@NgModule({
   declarations: [
      AppComponent,
      TestComponent
   ],
   imports: [
      BrowserAnimationsModule,
      BrowserModule,
      AccordionModule,
      AlertModule,
      ButtonsModule,
      FormsModule,
      CarouselModule,
      CollapseModule,
      BsDatepickerModule.forRoot(),
      BsDropdownModule,
      ModalModule,
      PaginationModule,
      PopoverModule,
      ProgressbarModule,
      RatingModule,
      SortableModule,
      TabsModule
   ],
   providers: [AlertConfig, 
      BsDatepickerConfig, 
      BsDropdownConfig,
      BsModalService,
      PaginationConfig,
      ProgressbarConfig,
      RatingConfig,
      DraggableItemService,
      TabsetConfig],
   bootstrap: [AppComponent]
})
export class AppModule { }

Update test.component.html to use the tabs component.

test.component.html

<tabset>
   <tab heading="Home">Home</tab>
   <tab *ngFor="let tabz of tabs"
      [heading]="tabz.title"
      [active]="tabz.active"
      (selectTab)="tabz.active = true"        
      [disabled]="tabz.disabled">
      {{tabz?.content}}
   </tab>
</tabset>

Update test.component.ts for corresponding variables and methods.

test.component.ts

import { Component, OnInit } from  @angular/core ;

@Component({
   selector:  app-test ,
   templateUrl:  ./test.component.html ,
   styleUrls: [ ./test.component.css ]
})
export class TestComponent implements OnInit {
   tabs = [
      { title:  First , content:  First Tab Content  },
      { title:  Second , content:  Second Tab Content , active: true },
      { title:  Third , content:  Third Tab Content , removable: true },
      { title:  Four , content:  Fourth Tab Content , disabled: true }
   ];
   constructor() {}
   ngOnInit(): void {
   } 
}
