<input type="text" />
Deprecated in Select2 4.0.
It is now encouraged to use the <select> tag instead.
In past versions of Select2, a <select> element could
only be used with a limited subset of options. An
<input type="hidden" /> was required instead, which did
not allow for a graceful fallback for users who did not have JavaScript
enabled. Select2 now supports the <select> element for
all options, so it is no longer required to use <input />
elements with Select2.
