Demo and documentation https://lokesh-coder.github.io/toppy/

Installation

step 1: Install from npm or yarn

npm install toppy // or
yarn add toppy

step 2: Import ToppyModule in your main module

import { ToppyModule } from 'toppy';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, ToppyModule], // <==
  bootstrap: [AppComponent]
})
export class AppModule {}

step 3: Import Toppy service in your component

import { Toppy } from 'toppy'; // <==

@Component({
  selector: 'app-root',
  template: '<div #el>Click me</div>'
})
export class AppComponent {
  @ViewChild('el', { read: ElementRef })
  el: ElementRef;

  constructor(private _toppy: Toppy) {}

  ngOnInit() {
    const position = new RelativePosition({
      placement: OutsidePlacement.BOTTOM_LEFT,
      src: this.el.nativeElement
    });

    this.overlay = this._toppy
      .position(position)
      .content('hello') // content
      .create();
  }

  open() {
    this.overlay.open();
  }

  close() {
    this.overlay.close();
  }
}

Content

Toppy allows to use string, html, TemplateRef, Component as overlay content.

Plain text

this.overlay = this._toppy
  .position(position)
  .content(`some plain text content`) // simple text
  .create();

HTML content

this.overlay = this._toppy
  .position(position)
  .content(`<div>any HTML content</div>`, { hasHTML: true }) // html
  .create();

Using TemplateRef

<ng-template #tpl>Hello world!</ng-template>
@ViewChild('tpl') tpl:TemplateRef<any>;

this.overlay = this._toppy
  .position(position)
  .content(this.tpl) // template ref
  .create();

Component

// host component
@Component({
  template: '<div>Hello</div>'
})
export class HelloComponent {}
this.overlay = this._toppy
  .position(position)
  .content(HelloComponent) // <==
  .create();

Dont forget to add host component in entryComponents in module

Positions

Position determines the location and size of the overlay. There are four positions:

Relative position

Overlay position that is relative to specific element. These are used in tooltips, popovers, dropdowns, menus

new RelativePosition({
  src: HTMLElement, // target element
  placement: OutsidePlacement, // location of the content
  width: string | number, // content width eg, `auto`, 150, `30%`
  height: string | number, // content height eg, `auto`, 150, `30%`
  autoUpdate: boolean // update position when window scroll/resize/drag
});

Relative position supports 12 placements:

OutsidePlacement.BOTTOM;
OutsidePlacement.BOTTOM_LEFT;
OutsidePlacement.BOTTOM_RIGHT;
OutsidePlacement.LEFT;
OutsidePlacement.LEFT_BOTTOM;
OutsidePlacement.LEFT_TOP;
OutsidePlacement.RIGHT;
OutsidePlacement.RIGHT_BOTTOM;
OutsidePlacement.RIGHT_TOP;
OutsidePlacement.TOP;
OutsidePlacement.TOP_LEFT;
OutsidePlacement.TOP_RIGHT;

Global position

Overlay position that is relative to window viewport. These are used in modals, alerts, toastr

new GlobalPosition({
  placement: InsidePlacement, // location of the content.
  width: string | number, // content width eg, `auto`, `150`, `30%`
  height: string | number, //content height eg, `auto`, 150, `30%`
  offset: number // oustide space of the content, in px
});

Global position supports 9 placements:

InsidePlacement.BOTTOM;
InsidePlacement.BOTTOM_LEFT;
InsidePlacement.BOTTOM_RIGHT;
InsidePlacement.LEFT;
InsidePlacement.RIGHT;
InsidePlacement.TOP;
InsidePlacement.TOP_LEFT;
InsidePlacement.TOP_RIGHT;
InsidePlacement.CENTER;

Slide position

Overlay position that is relative to window viewport. These are used in side panels, sidebars, blade

new SlidePosition({
  placement: SlidePlacement, // rigth or left
  width: string // width eg, '300px' or '30%'
});

Slide position supports 2 placements:

SlidePlacement.LEFT;
SlidePlacement.RIGHT;

Fullscreen position

Overlay that occupies complete size of the viewport.

new FullScreenPosition();

Configuration

this.toppy
  .position(position: ToppyPosition)
  .config(configuration: ToppyConfig = {})
  .content('hello')
  .create();
property for
backdrop boolean · whether to show backdrop layer · default: false
closeOnEsc boolean · clicking Escape button will close overlay · default: false
closeOnDocClick boolean · dismiss on clicking outside of content · default: false
listenWindowEvents boolean · auto adjust the position on scroll/resize · default: true
containerClass string · overlay container class name · default: t-overlay
wrapperClass string · overlay wrapper class name · default: ''
backdropClass string · overlay backdrop class name · default: ''
bodyClass string · body class when overlay is open · default: t-open
windowResizeCallback function · triggered on window scroll
docClickCallback function · triggered on document click

Component communication

Component Data

When you host a component, you can control the overlay through ToppyOverlay service. Using this service you can access all properties that is provided in content. Also the properties comes with close.

this.overlay = this._toppy
  .position(position)
  .content(HelloComponent, { propName: 'toppy-test-prop' })
  .create();

this.overlay.listen('t_compins').subscribe(comp => {
  console.log('component is ready!', comp); // returns HelloComponent
});
// host component
@Component({
  template: '<div>Some text</div>'
})
export class HelloComponent {
  constructor(public overlay: ToppyOverlay) {
    console.log(this.overlay.props.propName); // will return 'toppy-test-prop'
  }

  close() {
    this.overlay.close();
  }
}

Template Data

This is very similar to above one. When you use template as a content, you can pass additional data to it.

this.overlay = this._toppy
  .position(position)
  .content(template, { name: 'Johny' })
  .create();

Then in your template you can refer the data like this,

<ng-template #tpl let-toppy>
  <div>Hello <span [innerText]="toppy.name"></span> !</div>
  <button (click)="toppy.close()">Close</button>
</ng-template>

Method close is automatically binded.

Plain text

When you use Plain text as a content, optionally you can able to set a class name to that div block.

this.overlay = this._toppy
  .position(position)
  .content('some content', { class: 'tooltip' })
  .create();
