Add to the documentation of Select2TagWidget that it accepts user input

[mardukbp]

The Select2TagWidget implements the oddly named tagging feature of Select2, which allows for dynamic option creation.

This is a widget that some people would like to use (myself included) , but since it is not properly documented they cannot find it and end up rolling their own.

Hi @mardukbp,

Thanks for reaching out and for your feedback. You know what they say. There are only two hard things left in computer science: cache invalidation & naming things.

I would be careful to rename the classes unless we add proper deprecation, but I am also not opposed.
What we definitely can do, is use a different language in the documentation, to ensure more search hits from users wanting to solve this use case.

Please don't hesitate to open a documentation PR. They are always most welcome!

Cheers,
Joe

I agree with you that renaming the classes is complicated. Improving the documentation is a better way. I just created the PR #291.

Thank you for your quick reply and your openness to contributions :)
