Install ng-tooltip via npm by running this command:

$ npm install @independer/ng-tooltip --save

Add TooltipModule to your main app.module.ts

// app.module.ts

import { TooltipModule } from  '@independer/ng-tooltip';
...
  
@NgModule({
  imports: [
    ...,
    TooltipModle.forRoot() // This .forRoot() is necessary
  ],
  ...
})
export class AppModule { }

Add <ind-tooltip-container></ind-tooltip-container> into your app main template, app.component.html. This tooltip container will be the parent DOM element where all the tooltips will be appended inside.

<!--app.component.html -->

<router-outlet></router-outlet>
<ind-tooltip-container></ind-tooltip-container>

You can assign any element to be the tooltip trigger. If you don't, by default the tooltip trigger will be a question mark icon like this:

The icons are available in 3 different sizes sm, md, lg

Tooltip with icon lg <ind-tooltip content="This is a simple tooltip which uses content attribute" size="lg"></ind-tooltip\>
Tooltip with icon md <ind-tooltip content="This is a simple tooltip which uses content attribute" size="md"></ind-tooltip\>
Tooltip with icon sm (default) <ind-tooltip content="This is a simple tooltip which uses content attribute" size="sm"></ind-tooltip>

You can also specify any custom HTML element as the tooltip trigger and the trigger will not be the circle question mark icon anymore.

<ind-tooltip content="Tooltip without question mark">
  <a>Click this link!</a> 
</ind-tooltip\>

Inside the tooltip you can write optionally header and content separately.

<ind-tooltip header="This is tooltip header" content="Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem Ipsum."></ind-tooltip>

It is also possible to have custom HTML content inside the tooltip by declaring <ng-template #tooltipContentTemplate></ng-template> inside <ind-tooltip></ind-tooltip>. The hash tooltipContentTemplate will mark it as HTML content inside tooltip, so it msut be written exactly the same.

<ind-tooltip header="This is a tooltip with HTML elements"> 
  <ng-template #tooltipContentTemplate> 
    Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum. 
    <h4>And a button</h4\> 
    <button>A button</button\>
  </ng-template>
</ind-tooltip>
