Supported environments

  • jQuery 1.7.2+
  • Modern browsers (Chrome, Firefox, Safari)
  • Internet Explorer 8+

New features

Breaking changes

  • Select2 now uses the MIT license
  • The full build of Select2 no longer includes jQuery - You must include jQuery separately on your page.
  • Select2 will prevent the inner scrolling of modals (and other scrollable containers) when it is open to prevent the UI from breaking. Read more at the commit.
  • jQuery is no longer listed as a dependency in the bower.json/component.json files.
  • <select> has replaced <input type="hidden" /> for all options (including remote data)
  • The matcher has been revamped to include full context, a compatibility module (select2/compat/matcher) has been created
  • The display always reflects the order data is sent to the server
  • The click mask is no longer the default (again). You can get back the old functionality by wrapping your selectionAdapter with the ClickMask (select2/selection/clickMask) decorator.
  • Select2 no longer stops the propagation of events happening within the dropdown and selection. You can use the StopPropagation modules available in the full builds to prevent this. [8f8140e3b0/]
  • The enter key no longer toggles the state of multiple select items in the results, but instead will only select them. Use CTRL + Space instead to toggle the state. [017c201094/]
  • Warnings will now be triggered in the developer console if Select2 detects an unsupported configuration.

Options

  • The default value of the width option has been changed from style to resolve.
  • The copy value for the width option has been renamed to style.
Renamed
  • formatSelection -> templateSelection
  • formatResult -> templateResult
  • sortResults -> sorter
  • createSearchChoice -> createTag
  • selectOnBlur -> selectOnClose
  • ajax.jsonpCallback -> ajax.jsonp
  • ajax.results -> ajax.processResults
  • tags: [array,of,data] -> data: [array,of,data], tags: true
  • placeholderOption has been replaced by placeholder.id (placeholder -> placeholder.text)
Internationalization
  • formatNoMatches -> language.noMatches
  • formatSearching -> language.searching
  • formatInputTooShort -> language.inputTooShort
  • formatInputTooLong -> language.inputTooLong
  • formatAjaxError -> language.errorLoading
  • formatLoading -> language.loadingMore
  • formatSelectionTooBig -> language.maximumSelected
Deprecated/Removed
  • initSelection - This is no longer needed with <select> tags. Limited backwards compatibility in the full build.
  • id - Data objects should now always have id and text attributes that are strings, use $.map when migrating
  • query - Use a custom data adapter instead. Limited backwards compatibility in the full build.
  • ajax.params - All parameters passed to ajax will be passed to the AJAX data transport function

Methods

Renamed
  • .select2("val", [value]) -> .val([value])
  • .select2("enable", !disabled) -> .prop("disabled", disabled)
Removed
  • .select2("onSortStart") and .select2("onSortEnd") - A custom selection adapter should be created instead
  • .select2("data", data) - Create the <option> tags for the objects that you would like to set, and set the .val to select them
  • .select2("readonly") - There is no way to make a <select> element read-only, disable it instead
