creating html nav-tabs dynamic in angular 6

Question

I am very new to angular 6, I have created tabs in HTML and I need to convert it in angular 6 and also make it dynamic. below is my HTML code-

<ul class="nav nav-tabs side_nav" role="tablist">
  <li role="presentation" class="dashboard_li active">
     <a href="#one" class="coin_name" aria-controls="one" role="tab" data-toggle="tab"></a>
  </li>
  <li role="presentation" class="dashboard_li">
    <a href="#two" class="coin_name" aria-controls="two" role="tab" data-toggle="tab"></a>
  </li>
</ul>
<div class="tab-content">
  <div role="tabpanel" class="tab-pane active" id="one"></div>
  <div role="tabpanel" class="tab-pane active" id="two"></div>
</div>

I have converted it angular 6, below is my angular code -

<ul class="nav nav-tabs side_nav" role="tablist">
  <li *ngFor="let wallet of coinwallet; let first = first;" [ngClass]="{firstItem: first}" role="presentation" class="accounts_li" [class.active]="selectedwallet===wallet">
    <a (click)="selectedwallet = coinwallet" aria-controls="one" role="tab" data-toggle="tab"></a>
  </li>
</ul>

<div class="tab-content">
  <div role="tabpanel" class="tab-pane active" id="one"></div>
  <div role="tabpanel" class="tab-pane active" id="two"></div>
</div>

Now I have two pints here - 1- how would I make tab-content dynamic according to tabs 2- Currently tabs are not working, as I am changing from one tab to another tab, tab-content always remain same, it's not changing according to the tab. Any help would be appreciated. Thanks in advance.

Answer 1

you need to show/hide tab-content using *ngIf angular directive

<ul class="nav nav-tabs side_nav" role="tablist">
  <li *ngFor="let wallet of coinwallet; let first = first;" [ngClass]="{firstItem: first}" role="presentation" class="accounts_li" [class.active]="selectedwallet===wallet">
    <a (click)="selectedwallet = wallet" aria-controls="one" role="tab" data-toggle="tab">{{wallet}}</a>
  </li>
</ul>

<div class="tab-content">
  <div *ngIf="selectedwallet === coinwallet[0]" role="tabpanel" class="tab-pane active" id="one">wallet 1 content</div>
  <div *ngIf="selectedwallet === coinwallet[1]" role="tabpanel" class="tab-pane active" id="two">wallet 2 content</div>
</div>

.ts:

  coinwallet: string[] = ['wallet1','wallet2'];
  selectedwallet = this.coinwallet[0];
