Loading Array Data

Select2 provides a way to load the data from a local array. You can provide initial selections with array data by providing the option tag for the selected values, similar to how it would be done for a standard select.

Loading Remote Data

Select2 comes with AJAX support built in, using jQuery's AJAX methods. In this example, we can search for repositories using GitHub's API.

Localization

Select2 supports displaying the messages in different languages, as well as providing your own custom messages that can be displayed. The language does not have to be defined when Select2 is being initialized, but instead can be defined in the [lang] attribute of any parent elements as [lang="es"].

RTL support

Select2 will work on RTL websites if the dir attribute is set on the <select> or any parents of it. You can also initialize Select2 with dir: "rtl" set.

Diacritics support

Select2's default matcher will ignore diacritics, making it easier for users to filter results in international selects. Type "aero" into the select below.

Template support

Select2 supports custom themes using the theme option so you can style Select2 to match the rest of your application. These are using the classic theme, which matches the old look of Select2.

Templating

Various display options of the Select2 component can be changed: You can access the <option> element (or <optgroup>) and any attributes on those elements using .element. Templating is primarily controlled by the templateResult and templateSelection options.

Multiple Select Options

Tagging Support

Select2 can be used to quickly set up fields used for tagging. Note that when tagging is enabled the user can select from pre-existing options or create a new tag by picking the first choice, which is what the user has typed into the search box so far.

Automatic Tokenization

Select2 supports ability to add choices automatically as the user is typing into the search field. Try typing in the search field below and entering a space or a comma. The separators that should be used when tokenizing can be specified using the tokenSeparators options.

Customizing How Results Are Matched

Unlike other dropdowns on this page, this one matches options only if the term appears in the beginning of the string as opposed to anywhere: This custom matcher uses a compatibility module that is only bundled in the full version of Select2. You also have the option of using a more complex matcher.
