Squeezebox

Simple Angular 2 accordion component with smooth transitions/animations

Live Sample

Running sample can be seen here , but this is not for real use case, so for real usage take a look at the following references: installation via npm, typescript usage, etc

Installation via npm

npm install squeezebox --save

Typescript Usage

Import the module wherever is going to be used:

import {SqueezeBoxModule} from 'squeezebox/dist';

Import the module also in your app module, like:

@NgModule({
  imports:      [BrowserModule, SqueezeBoxModule], // here
  declarations: [AppComponent],
  bootstrap:    [AppComponent]
})
export class AppModule { }

Start using it in the component template:

<squeezebox>
    <sb-item>
        <sb-item-head>Title 1</sb-item-head>
        <sb-item-body>Lorem ipsum dolor sit amet</sb-item-body>
    </sb-item>
</squeezebox>

or iterate a data list

<squeezebox>
    <sb-item  *ngFor="let item of itemsList">
        <sb-item-head>{{item.title}}</sb-item-head>
        <sb-item-body>{{item.description}}</sb-item-body>
    </sb-item>
</squeezebox>

Inputs

• multiple:boolean (default: true) => this attribute enable/disable the multiple item expanded at the same time, for example: ... <squeezebox [multiple]="false"> ...
• collapsed:boolean (default: true) => this attribute enable/disable collapse from the beginning when component is rendered, for example: ... <sb-item [collapsed]="false"> ...
• collapsed:boolean (default: true) => this attribute enable/disable collapse from the beginning when component is rendered, for example: ... <sb-item [collapsed]="false"> ...

Outputs

• onToggled => this output is triggered everytime item is expanded or collapsed, returns true if collapsed or false if expanded, for example:

  
  <sb-item  *ngFor="let item of itemsList" (onToggled)="itemWasToggled($event)">
  ...
  </sb-item>

...

itemWasToggled(event) { console.log('collapsed:', event); } ...

### Methods
*   **refresh** => This method is useful when accordion is hidden for example when using tabs or panels that go visible and hidden. It can be called from a SqueezeBox reference via `@ViewChild` or `@ViewChildren`, for example following code can refresh all the available squeezeboxes in the current component :

... @ViewChildren(SqueezeBox) squeezeboxes: QueryList; ...

... onTabActive(event:Event) { event.preventDefault(); this.squeezeboxes.toArray().forEach(function(s) { s.refresh(); }); } ...

### SystemJS configuration
Will need to [map](https://github.com/systemjs/systemjs/blob/master/docs/config-api.md#map) the module:

map: { "squeezebox": "npm:squeezebox", ... }

And set the package configuration:

packages: { ... squeezebox: { main: './index.ts', defaultExtension: 'ts' }, ...

If you are not compiling third party javascript, you can try the following configuration so you can use generated files:

squeezebox: { defaultExtension: 'js', main: 'index.js' }

### Styles
Styles needs to be included, imported or copied, also feel free to modify the styles:
