There are some common problems that developers may encounter when using working with Select2 for the first time. If you are new to Select2, please consult the common problems section of the documentation first.
If you don’t find what you’re looking for there, then please check the the forums, Stack Overflow and existing issues, both opened and closed. Your question may have already been asked and answered before!
In general, the Github issue tracker should only be used for bug reports and feature requests. If you’re just having trouble getting something to work, you should ask in the forums or on Stack Overflow instead.
Tag your question with the jquery-select2
tag, and optionally with tags relevant to other technologies involved, such as jquery
or another client-side framework. You should also mention the version of Select2 that you are using.
We really appreciate clear bug reports that consistently show an issue within Select2. If you are reporting a bug, you must follow these steps:
Select2 is a large library that carries with it a lot of functionality. Because of this, many feature requests will not be implemented in the core library.
Before starting work on a major feature for Select2, post to the forums first or you may risk spending a considerable amount of time on something which the project developers are not interested in bringing into the project.
Select2 is made up of multiple submodules that all come together to make the standard and extended builds that are available to users. The build system uses Node.js to manage and compile the submodules, all of which is done using the Grunt build system.
Select2 can be built and developed on any system which supports Node.js. You can download Node.js at their website.
All other required Node.js packages can be installed using npm, which comes bundled alongside Node.js.
cd /path/to/select2/repo
npm install
You may need to install libsass
on your system if it is not already available in order to build the SASS files which generate the CSS for themes and the main component.
Select2 uses the Grunt build task system and defines a few custom
tasks for common routines. One of them is the compile
task, which compiles
the JavaScript and CSS and produces the final files.
cd /path/to/select2/repo
grunt compile
You can also generate the minified versions (.min.js
files) by executing the
minify
task after compiling.
cd /path/to/select2/repo
grunt minify
Select2 uses the QUnit test system to test individual components.
cd /path/to/selct2/repo
grunt test
The documentation for Select2 is maintained in a separate repository. Select2.org is built with the flat-file CMS Grav, using their RTFM skeleton.
The documentation files themselves are written in Markdown, and can be found in the pages/
subdirectory. You can submit pull requests to the develop
branch of the repo.
If you’d like to set up a local instance of the entire documentation website, you must first have a web server (Nginx, Apache, etc) and PHP installed locally. Then, follow these steps:
This application uses the Grav CMS. This repository does not contain a full Grav installation - rather, it just contains the contents of Grav’s user
directory, which is where all of our content, themes, and assets live. This was done as per the recommendation on Grav’s blog, to make it easier to deploy changes to the live server.
To install this website on your computer, first install grav core in a project folder called select2-docs
under your webserver’s document root folder. Then, find the user
folder inside of your project folder. Delete the contents of the user
folder and clone this repository directly into the user folder.
When you’re done it might look something like this:
htdocs/
└── select2-docs/
├── assets/
├── ...
├── user/
├── .git
├── accounts/
├── assets/
├── config/
└── ...
└── ...
Grav needs your webserver to be able to write to certain directories. Make sure that backup/
, cache/
, images/
, logs/
, and tmp/
are all writeable by the user account under which your webserver runs.
Visit the local installation in your browser! For example, http://localhost/select2-docs.
We use GitHub’s pull request system for submitting patches. Here are some guidelines to follow when creating the pull request for your fix.
src/
). Do not make changes directly to files in the dist
directory.By following these steps, you will make it easier for your pull request to be reviewed and eventually merged.
Anyone can help the project maintainers triage issues and review pull requests.
Select2 regularly receives new issues which need to be tested and organized.
When a new issue that comes in that is similar to another existing issue, it
should be checked to make sure it is not a duplicate. Duplicates issues should
be marked by replying to the issue with “Duplicate of #[issue number]” where
[issue number]
is the url or issue number for the existing issue. This will
allow the project maintainers to quickly close off additional issues and keep
the discussion focused within a single issue.
If you can test issues that are reported to Select2 that contain test cases and confirm under what conditions bugs happen, that will allow others to identify what causes a bug quicker.
It is very common for pull requests to be opened for issues that contain a clear solution to the problem. These pull requests should be rigorously reviewed by the community before being accepted. If you are not sure about a piece of submitted code, or know of a better way to do something, do not hesitate to make a comment on the pull request.
If you come across tickets which have not been updated for a while, you are encouraged to revive them. If you do, please include more information in your comment on the issue. Common bugs and feature requests are more likely to be fixed, whether it is by the community or the developers, so keeping tickets up to date is encouraged.
It should also be made clear that all code contributed to Select must be licensable under the MIT license. Code that cannot be released under this license cannot be accepted into the project.
