core

This library was generated with Nx and floating-ui for Angular applications.

To see a demo, click on the link provided.

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 {
}

| Method | Description | Type | |-------------------|-------------------------------------------------------------------------------|-------------------------| | computePosition | The computePosition method is a proxy for computePositionfrom floating-ui | ComputePositionReturn | | autoUpdate | The autoUpdate method is a proxy for autoUpdate from floating-ui | cleanup function |

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.

ClickOutside directive

The click outside directive manages clicks inside and outside HTMLElements. This directive is used by the ngx-floating component.

To see a demo, click on the link provided.

Usage

import { ClickOutsideDirective, ClickOutsideEvent } from '@ngx-popovers/core';

@Component({
  selector: 'ngx-click-outside-example',
  standalone: true,
  imports: [ClickOutsideDirective],
  template: `
    <div
      (ngxClickOutside)="onClick($event)"
      (inside)="onInsideClicked($event)"
      (outside)="onOutsideClicked($event)"
    ></div>
  `
})
export class ClickOutsideExample {
  onClick(event: ClickOutsideEvent) {
    console.log('Click!', el);
  }

  onInsideClicked(el: EventTarget) {
    console.log('Inside click!', el);
  }

  onOutsideClicked(el: EventTarget) {
    console.log('Outside click!', el);
  }
}

API

Inputs

| Input | Description | Type | Default | |--------------|---------------------------------------------------------------|--------------------------------------|---------------------| | placement | controls the position of the floating relative to the trigger | Placement | bottom | | middleware | list of middleware from floating-ui | MiddlewareList | offset(4), flip() | | autoUpdate | updates floating element automatically | boolean | true | | bindTo | renders floating element as last child of bindTo | string | HTMLElement | .body | | strategy | This is the type of CSS position property to use | absolute | fixed | undefined | undefined |

Outputs

| Output | Description | Type | |-------------------------|----------------------------------------------------------------------|-------------------------| | clickedOutside | emits when user clicks outside the floating element | Element | | clickedInside | emits when user clicks inside the floating element | Element | | computePositionReturn | emits every time when the floating component calls computePosition | ComputePositionReturn |

Configuration

There is a configuration token NGX_FLOATING_CONFIG. Please use the NgxFloatingConfig class to change the default floating properties.

export const FloatingConfigProvider: Provider = {
  provide: NGX_FLOATING_CONFIG,
  useValue: new NgxFloatingConfig({
    placement: 'top-end',
    arrow: true
  })
};

Arrow

The arrow component adds an arrow to the floating component.

<div #trigger>Trigger</div>

<ngx-floating
  [reference]="trigger"
>
  <p>Floating content</p>

  <ngx-arrow padding="10" />
</ngx-floating>

To see a demo, click on the link provided.

You can provide your own component for arrow visualization:

@Component({
  standalone: true,
  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',
  styleUrl: './app.component.scss',
  providers: [ArrowProvider]
})
