A Select2 v4 Theme for Bootstrap 3
select2-bootstrap-theme version License

Demonstrations available at select2.github.io/select2-bootstrap-theme

Compatibility

Built and tested with Bootstrap v3.3.7 and Select2 v4.0.3 in latest Chrome, Firefox and Safari (Mac) and Internet Explorer 11 and 10.

Installation

You can download select2-bootstrap-theme from this GitHub repo, install it using Bower or npm, or source it directly from CDNJS.

Install using Bower or npm

You may install select2-bootstrap-theme with Bower or npm:

// Bower
bower install select2-bootstrap-theme

// npm
npm install select2-bootstrap-theme
Source select2-bootstrap-theme from CDNJS

select2-bootstrap-theme is also available on CDNJS.

Usage

select2-bootstrap-theme only works with Select2 v4.x. Applying the theme requires select2-bootstrap.css referenced after the default select2.css that comes with Select2:

<link rel="stylesheet" href="select2.css">
<link rel="stylesheet" href="select2-bootstrap.css">

To apply the theme, tell Select2 to do so by passing bootstrap to the theme option when initializing Select2:

$( "#dropdown" ).select2({
    theme: "bootstrap"
});

You may also set it as the default theme for all Select2 widgets like so:

$.fn.select2.defaults.set( "theme", "bootstrap" );

Changelog

0.1.0-beta.9
  • Built on Bootstrap 3 v3.3.7 and corresponding bootstrap-sass.
  • Prefixed all Sass and Less variables with s2bs to avoid conflicts and improve customizability as select2-bootstrap-theme does not "force" you to use (specific) Bootstrap Sass/Less variables anymore; a nice side effect is that we now also provide (a raw) documentation for the inherited Bootstrap variables in one place.
  • Added Sass and Less variables to override select2-bootstrap-themes default font-size, color and vertical padding for .select2-results__group. [#19]
  • Added Sass and Less variables replacing hardcoded values in styles for .select2-selection__clear, .select2-selection__choice__remove and .select2-selection__choice.

Contributing

The project offers Less and Sass sources for building select2-bootstrap.css; both make use of variables from either Bootstrap (Less) or Bootstrap for Sass. The demo pages are built using Jekyll and there are a bunch of Grunt tasks to ease development.

With Jekyll, node.js and Less installed, run

npm install

to install all necessary development dependencies (Sass is compiled vLibSass/node-sass).

  • grunt build builds docs
  • grunt serve builds docs and serves them via Jekyll's --watch flag on http://localhost:4000

Develop in src/select2-bootstrap.scss and test your changes using grunt serve. Ideally, port your changes to lib/select2-bootstrap.less and make sure tests are passing to verify that both Less and Sass compile down to the target CSS via npm test.

grunt scss2less helps in converting the Sass source to its Less counterpart (and overwrites the existing src/select2-bootstrap.less), but doesn't do the full job – please review the changes to the Less source file and make the necessary adjustments.
