jquery.selectBoxIt.js - jQuery Select Box Plugin

A jQuery plugin that progressively enhances an HTML Select Box into a single option dropdown list. The dropdown list can be optionally styled with Twitter Bootstrap, jQueryUI ThemeRoller, or jQuery Mobile, optionally animated with jQueryUI show/hide effects, and works on Desktop, Tablet, and Mobile browsers.

##Requirements jQuery 1.8.3+ (It is always recommended to use the latest version of jQuery)

jQueryUI Widget Factory 1.10.0+ (It is always recommended to use the latest version of the jQueryUI Widget Factory)

##Desktop Browser Support IE8+, Firefox 4+, Chrome, Safari 4+, Opera 11+ (Other browsers may work, but I did not test on them)

Note: The CSS3 background-size property is used for the icon images, which is only supported in IE9+

##Mobile/Tablet Browser Support iOs 3+, Android 2.1+ (Other browsers may work, but I did not test on them)

##Unit Tests All unit tests are written using the Jasmine Framework

##Contributing Take care to maintain the existing coding style. Add Jasmine unit tests for any new or changed functionality. Lint and test your code using grunt.

If you plan to contribute to SelectBoxIt in the future, keep in mind that you should make sure your code passes the Grunt checks.

To set up the SelectBoxIt grunt/node.js dependencies, first make sure you have PhantomJS installed, which is a headless browser. Unfortunately PhantomJS cannot be installed automatically.

Next, navigate to within the jquery.selectBoxIt.js folder and type `npm install' (this should install grunt and a few other node.js libraries).

Next, type grunt

Note: If you are on Windows, remember you need to run the grunt command using grunt.cmd. Also, if you have trouble getting the Jasmine Unit Tests to work with PhantomJS 1.5 (the current release), install PhantomJS 1.3.

After you have verified your code, send a pull request to the SelectBoxIt dev branch. After you send a pull request, you will hear back from me shortly after I review your code.

You'll find source code in the "src" subdirectory!

##Forking If you find that you need a feature that SelectBoxIt does not currently support, either let me know via the SelectBoxIt issue tracker, or fork SelectBoxIt on Github and easily extend SelectBoxIt to create your own widget!

##Change Log

3.8.0 - October 4, 2013

Bug Fixes

• Fixed mobile hidden select box with bug: #209
• Prevent disabled Selects from being clickable on iOS devices: #203
• Fixed defaultText mobile bug: #205

Improvements

• Improved performance by not removing option icons #207
• Allow passing in a custom theme object #204

3.7.0 - August 13, 2013

Bug Fixes

• Fixed a focus bug that prevented a drop down option to be selected if the drop down menu was open and the page was then scrolled.
• Fixed scroll list not closing bug #196 #191
• Fixed incorrect Microsoft CSS prefix: #195
• Fixed max-width rendering for select boxes that are initially hidden: #192
• Fixed Native select box and accesibility bug: #189

Improvements

• ARIA support #197

3.6.0 - June 23, 2013

BREAKING CHANGES

• jQuery v1.8.3 or greater is now required. The reason for the bump is a jQuery bug associated with passing an array of jQuery objects to the append() method. #175

• The size attribute is no longer supported. You must now use the data-size attribute to specify size. The reason for the change is because when an HTML select box has a size attribute, you cannot retrieve the value of the select box (terrible) #170

New Options

• hideCurrent - Hides the currently selected drop down option from the list. #172

Bug Fixes

• Prevent the destroy event from propagating to parent elements #181
• Fixed an irritating bug that did not allow an option to be selected after the drop down was open and the page was scrolled

Improvements

• Deferred objects/promises are now supported within the populate option and add() method. This change makes it much easier to use the jQuery ajax() method to dynamically add options. #171
• When using the showFirstOption option with mobile/tablet browsers, the first drop down option will now be disabled. Since hiding a select box option is not in the W3C specification, it will not yet be supported. #179
• On mobile/tablet browsers, the option-click event is now triggered along with the change event. #184
• Improved the setOption() and setOptions() methods to handle all option updates. #185

3.5.0 - May 10, 2013

An option will only be selected when a user clicks an option or presses the enter key when an option is actively "focused". #85
