NgWormhole

This component allows rendering all of its content to be rendered elsewhere on the page.

Why?

Sometimes a dialog or tooltip has to be rendered outside of an element, as CSS stacking contexts may interfere with positioning.

Installation

$ yarn add ng-wormhole

Import NgWormholeModule in your app:

import { NgModule } from '@angular/core';
import { NgWormholeModule } from 'ng-wormhole';

@NgModule({
  imports: [NgWormholeModule]
})
export class AppModule {}

Example usage

index.html

<body>
  <my-angular-app></my-angular-app>
  <div id="wormhole-target"></div>
</body>

In a component template:

<my-popover *ngWormhole="'#wormhole-target'">...</my-popover>

The <my-popover> component will then be rendered in the #wormhole-target element, it will also automatically cleaned up once your component will be destroyed.

Inputs

ngWormhole: selector or element Which element to append to.

<div #targetElement id="my-target"></div>
<my-popover *ngWormhole="targetElement">...</my-popover>
<!-- or by id/selector -->
<my-popover *ngWormhole="'#my-target'">...</my-popover>

renderInPlace: boolean = false Should the component render its children in place?

<my-popover *ngWormhole="'#wormhole-target'; renderInPlace: true">...</my-popover>
