Bootstrap Dual List Box

Synopsis

Bootstrap Dual List Box is a dual list box implementation especially designed for Bootstrap and jQuery. This control is quite easy for users to understand and use. Also it is possible to work with very large multi-selects without confusing the user.

Usage

First off you should create a simple <select id="some-name"> tag. After which you can initialize the dual list box as a jQuery plugin like so: $('some-name').DualListBox();. There are also some options associated with this plugin.

Options / API

There are currently two ways to use this component. First up is by using html5 data-* attributes embedded in the select tag, but you can also provide a Javascript Object. The variable names are the same all around and can be even mixed and matched within the select or Javascript. The current options are:

Option	Type	Default	Description
json	Boolean	true	Whether to download the data via a JSON request.
uri	URI	local.json	The relative or absolute URI where to receive the data from.
value	String	id	This determines what JSON field is handled as the value.
text	String	name	This determines what JSON field is handled as the text.
title	String	Example	The title of the control.
horizontal	Boolean	false	Whether the control is lay out horizontal or vertical.
timeout	UInt	500	Timeout when to start searching with the filter.
textLength	UInt	45	Maximum text length of when the element should contain title-attributes.
moveAllBtn	Boolean	true	Whether to display the move all button (from left to right or vice-versa).
maxAllBtn	UInt	500	Integer to determine from which length to display the warning message below.
warning	String	<...>	Warning message that is displayed when trying to move large amounts of elements.
