FloatingService

Before use, ensure this service is added to the providers list.

You can import the FloatingService from '@ngx-popovers/core'.

Example usage:

import { FloatingService } from '@ngx-popovers/core';

@Component({
  standalone: true,
  providers: [FloatingService],
  template: '',
  styles: ''
})
export class AppComponent {
}

floatingService = inject(FloatingService);

this.floatingService.computePosition(trigger, floating);

You can also import all types and methods from floating-ui from this package:

import {
  Derivable,
  FlipOptions,
  OffsetOptions,
  Placement,
  ShiftOptions
} from '@ngx-popovers/core';

portal

To see a demo, click on the link provided.

Usage

The <ngx-portal/> component displays content on the body.

You can also display portal content within an element of your choice:

<div #portalWillBeInsideMe>
  <p>Portal content will be rendered after this tag</p>
  <!-- Here -->
</div>

<ngx-portal [bindTo]="portalWillBeInsideMe">
    <p>It will be displayed as the last child of the div</p>
</ngx-portal>

This component is essential for displaying tooltips correctly without overlapping with other elements on the page.

    placement: 'top-end',
    arrow: true
  })
};

Arrow

The arrow component adds an arrow to the floating component.

<div #trigger>Trigger</div>

  [trigger]="trigger"
>
  <p>Floating content</p>
  
  <ngx-arrow padding="10" />
</ngx-floating>

  template: `
    <div
      style="
        width: 5px;
        height: 5px;
        transform: rotate(45deg);
        background: indianred;
      "
    ></div>
  `
})
export class CustomArrow extends FloatingArrowBase {
}

export const ArrowProvider: Provider = {
  provide: NGX_ARROW_COMPONENT,
  useValue: CustomArrow
};

Any module:

@Component({
  standalone: true,
  selector: 'app',
  templateUrl: './app.component.html',
