What it is
Select2 is a JavaScript component that replaces the standard dropdown (select) box on a web page with a more capable one. It adds search, lets options be loaded from remote data sources, and supports loading more results as the user scrolls. It is built on jQuery and is typically included on a page from a CDN or installed as a package.
- Add search to a long native select list
- Build a multi-select with a cleaner interface
- Load items from an AJAX endpoint and make them searchable
- Allow users to add new tags on the fly
Great for
- Web developers who already use jQuery and want a better dropdown
- Sites with long option lists that need search
- Forms that load options from a server through AJAX
- Projects using a CMS or framework integration listed in the README
Not ideal for
- Projects that do not use jQuery, since the library is built on it and the README does not describe a non-jQuery version
- Non-developers who want a finished tool without writing any code
- Situations where a plain native select element is enough
How to get it
- 1
See the README
You'll need: jQuery
Clone the repository
git clone https://github.com/select2/select2.git - 2
Run it
- Include jQuery on the page
- Include dist/js/select2.js from a CDN or downloaded copy
- Optionally include a language file such as dist/js/i18n/nl.js after select2.js
- Call .select2() on a select element, following the examples at select2.org
- 3
Get the most out of it
- Use a language file from dist/js/i18n/ for localized messages
- Pick a theme for your CSS framework, such as the Bootstrap 4 or 5 themes listed in the README
- Use the AJAX options to load large datasets based on the search term
- Check the MkDocs-based docs in the repository for configuration details
Downloads
Strengths
- Covers common needs like search, tagging, and remote data in one component
- Works as a drop-in enhancement for existing select elements
- MIT licensed and widely integrated with platforms such as Django, Drupal, and Rails
Trade-offs
- Depends on jQuery, which may be an unwanted dependency in modern projects
- README lists older browser support (IE 8+), which may be more than needed today
- Latest release shown is 4.1.0 with no binaries; usage is through CDN or source files
