Ng-Collapsible

A simple Angular component (as directive) for collapse. No dependencies, no need for Bootstrap or jQuery. See working example: here.

How to Use

  • Install: npm i ng-collapsible --save
  • Import to your @NgModule or any other module file : import { NgCollapsibleModule } from 'ng-collapsible';
  • Add to the module import sections: imports: [ BrowserModule, NgCollapsibleModule]
  • Add the attribute ngCollapsible to your element:
    <div ngCollapsible>
        <h4>Simple Collapsible: </h4>
        <li *ngFor="let item of items">{{item}}</li>
    </div>

    Note: ngCollapsible will use the first element as a clickable header and the other as the collapsible items.

Component Inputs

isOpen

Use [isOpen] to programmatically close or open the collapse items:

<div ngCollapsible [isOpen]="true">
    <h4>Start Open Collapsible:</h4>
    <div *ngFor="let item of items">{{item}}</div>
</div>

ngCollapseOptions

Pass an object of type NgCollapsibleOptions to [ngCollapseOptions] in order to customize some behavior:

interface NgCollapsibleOptions {
    showArrow?: boolean;
    arrowSide?: NgCollapsibleArrowSide;
    accessibility?: boolean;
    iconSet?: NgCollapsibleIconSet;
    accordion?: boolean;
}

Options

  • showArrow: boolean - choose if to add an icon to the header. default true
  • arrowSide: NgCollapsibleArrowSide - choose the side of the icon. default start
  • accessibility: boolean - choose to add an accessibility attributes to the clickable header and the collapse items. default true
  • iconSet: NgCollapsibleIconSet - choose an icon set. default ionic
  • accordion: boolean - declare the element as a part of accordion, to close it when other accordion element will open. default false

Helpers

You have few interfaces and enums to help you fill NgCollapsibleOptions, all importable:

export enum NgCollapsibleArrowSide {
    start = 'start',
    end = 'end'
}
 
export enum NgCollapsibleIconSet {
    ionic = 'ionic',
    md = 'md',
    plusMinus = 'plus-minus'
}

Style

For compatibility the encapsulation of the component sets to ViewEncapsulation.None This way you can apply any style to any element even from your global css file. The component uses few css classes, you can override them and set your own style:

.ngCollapseHeaderBox.ngCollapseHeader.ngCollapseIcon.ngCollapseItems

To change the style of the icon change .ngCollapseIcon svg style.

Compatibility

Tested with Angular 8 and Ionic 3 with Angular 5.
