javascript select2 allowed tags

Question

I need to allow users select ONLY allowed tags in select.

Currently I have that:

$("input#id_txtcolor").select2({tags:["red", "green", "blue"]});

Can you help me please with that?

Answer 1

as of 3.3 you can specify your own createSearchChoice when using tags that will always return null, thus preventing the default choice from being created.

$().select2({
    createSearchChoice: function() { return null; },
    tags:...
});
