Advance Options

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.

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.

Programmatic access

Select2 supports methods that allow programmatic control of the component.

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.
