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. |
