ngx-accordion

Simple accordion control for your angular2 applications using bootstrap3. Does not depend of jquery. If you don't want to use it without bootstrap - simply create proper css classes. Please star a project if you liked it, or create an issue if you have problems with it.

Installation

1. Install npm module:

   npm install ngx-accordion --save

2. If you are using system.js you may want to add this into map and package config:

   {
       "map": {
           "ngx-accordion": "node_modules/ngx-accordion"
       },
       "packages": {
           "ngx-accordion": { "main": "index.js", "defaultExtension": "js" }
       }
   }

Usage

Import AccordionModule in your app and start using component:

<accordion [showArrows]="true" [closeOthers]="false" [expandAll]="true">
    <accordion-group heading="Accordion heading">
        <accordion-heading>
            Or <b>custom</b> <accordion-toggle>heading with clickable zone.</accordion-toggle>
        </accordion-heading>
        Accordion group contents.
    </accordion-group>
    ...
</accordion>

• <accordion>:

  Contains accordion groups.

  • [showArrows]="true|false" Indicates if arrows should be shown or not. Default is false
  • [closeOthers]="true|false" Indicates if other opened groups should be automatically closed when you open a new group. Default is true
  • [expandAll]="true|false" Indicates if all panels should be expanded by default. Default is false. If expandAll is set to true, then the closeOthers option has no effect, since all panels are opened.

• <accordion-group>:

  Used inside <accordion> and represents a single collapsible panel.

  • heading="Group heading" Simple text group heading
  • [disabled]="true|false" Indicates if this group is disabled or not (expandable or not)
  • (onOpen)="doSomethingOnOpen()" Calls function when this accordion-group is opened
  • (onClose)="doSomethingOnClose()" Calls function when this accordion-group is closed
  • (onToggle)="doSomethingOnToggle(isOpened)" Calls function when this accordion-group is toggled
  • <accordion-heading> Content zone where you can put custom headings

• <accordion-toggle>:

  Used inside <accordion-group> to provide a custom clickable zone for the accordion heading. This is usable when you have clickable controls in your header (for example checkbox) and you don't want accordion to be opened/closed on click of this controls.
