Angular - How to show tooltip on @ng-select/ng-select options

To show tooltips on options in an @ng-select/ng-select dropdown in Angular, you can use the Angular title attribute to provide the tooltip text. The title attribute is a standard HTML attribute that browsers use to display tooltips when the user hovers over an element.

Here's an example of how you can add tooltips to options in an @ng-select/ng-select:

Assuming you have an array of objects with value and tooltip properties:

// component.ts import { Component } from '@angular/core'; @Component({ selector: 'app-my-component', template: ` <ng-select [items]="items" bindLabel="value" bindValue="value"> </ng-select> ` }) export class MyComponent { items = [ { value: 'Option 1', tooltip: 'Tooltip for Option 1' }, { value: 'Option 2', tooltip: 'Tooltip for Option 2' }, { value: 'Option 3', tooltip: 'Tooltip for Option 3' }, // ... other items ]; }

Then in your template, use the title attribute to bind the tooltip:

<!-- component.html --> <ng-select [items]="items" bindLabel="value" bindValue="value"> <ng-template #optionTemplate let-item="item"> <span title="{{ item.tooltip }}">{{ item.value }}</span> </ng-template> </ng-select>

In this example, the ng-template with the #optionTemplate template reference is used to customize the rendering of the options. The title attribute is set to the tooltip property of each item.

Adjust the template according to your specific requirements and the structure of your data. This approach should work for showing tooltips on options in an @ng-select/ng-select dropdown.
