Topic: is it possible to create sub-tabs

Ken Wilson free asked 5 years ago


Expected behavior after initiating both 'main tab set' and 'sub tab set' i should be able to programatically access both sets. Actual behavior only first tabset gets defined Resources (screenshots, code snippets etc.)

@ViewChild('mainTabs',{ static: true }) mainTabs: TabsetComponent; @ViewChild('subTabs',{ static: true }) subTabs: TabsetComponent;

ngAfterViewInit(){ this.subTabs.setActiveTab(2); }

ERROR: returns an error stating: 'can not setActiveTab of undefined.'

Dear @Ken Wilson

Could you show me your HTML?

Dear @Ken Wilson

Make sure you use correctly @ViewChild decorator to get access to MdbTabset methods.

Here is my code with example, and everything works correctly (I don't get any error)

HTML:

<div class="container">
  <mdb-tabset #mainTabs [buttonClass]="'md-tabs tabs-orange tabs-3'" [contentClass]="'card'">
    <mdb-tab heading="Main tab">
      <div>Main Tab Content</div>
      <mdb-tabset #subTabs [buttonClass]="'md-tabs tabs-orange tabs-3'" [contentClass]="'card'">
        <mdb-tab heading="Sub tab">
          <div>Sub tab content</div>
          <mdb-tabset
            #selectedModelSubTabs
            [buttonClass]="'md-tabs tabs-orange tabs-3'"
            [contentClass]="'card'"
          >
            <mdb-tab *ngFor="let tab of tabs" heading="{{ tab.title }}">
              {{ tab.content }}
            </mdb-tab>
          </mdb-tabset>
        </mdb-tab>
      </mdb-tabset>
    </mdb-tab>

    <mdb-tab *ngFor="let tab of tabs" heading="{{ tab.title }}">
      {{ tab.content }}
    </mdb-tab>
  </mdb-tabset>
</div>

TS:

import { TabsetComponent } from 'your_path';
  @ViewChild('mainTabs', { static: true }) mainTabs: TabsetComponent;
  @ViewChild('subTabs', { static: true }) subTabs: TabsetComponent;
  @ViewChild('selectedModelSubTabs', { static: true }) selectedModelSubTabs: TabsetComponent;
  tabs: any[] = [{ title: 'Tab1', content: 'content 1' }, { title: 'Tab2', content: 'content 2' }];

  ngAfterViewInit() {
    this.mainTabs.setActiveTab(1);

    this.subTabs.setActiveTab(1);

    this.selectedModelSubTabs.setActiveTab(2);
  }

Hope it helps! Best Regards, Bartosz.
