Boost JS Collapse

A style-free and accessible collapse plugin for jQuery and Boost JS. While other plugins style everything for you, this plugin only handles the functionality, leaving the layout and styling up to you.

Installation

Install with npm:

npm install boost-js-collapse

Install in browser:

<script src="https://cdn.rawgit.com/marksmccann/boost-js-collapse/v0.0.1/dist/collapse.min.js"></script>

Usage

Create Plugin

var boost = require('boost-js');
// var boost = $.fn.boost; (browser install)
 
var collapse = require('boost-js-collapse');
// var collapse = $.fn.boost.collapse; (browser install)
 
$.fn.collapse = boost( collapse.plugin, collapse.defaults );

Markup Structure

<div id="collapse">
    <a href="#drawer1" data-bind="#collapse" data-role="handle">Handle 1</a>
    <div id="drawer1" data-bind="#collapse" data-role="drawer">Drawer 1</div>
    <a href="#drawer2" data-bind="#collapse" data-role="handle">Handle 2</a>
    <div id="drawer2" data-bind="#collapse" data-role="drawer">Drawer 2</div>
</div>

Note: data-bind is used to link the element to the instance, data-role is used to define the element's role in that instance. See Boost JS for more details.
