How to hide element in angular if one of the two condition is true

How to hide element in angular if one of the condition is true.

I tried with *ngIf=”productID == category.Lane || productID == category.Val”. It doesn’t work.

        placeholder="Select an option"
        <ng-option *ngFor="let product of products | orderBy: 'name'" value="{{ }}">{{ }}</ng-option>
      <div class="row" *ngIf="productID == category.Lane || productID == category.Val">
      <div class="col">

Method 1

With this condition:

*ngIf="productID == category.Lane || productID == category.Val"

You are saying, if first or second condition is truthy then show the element. If you want to hide it, in that case you should use the opposite condition:

*ngIf="!(productID == category.Lane || productID == category.Val)"

Method 2

Otherwise, you can use the hidden attribute instead of using *ngIf the condition

<div class="row" [hidden]="productID == category.Lane || productID == category.Val">
