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 {
}
}
