How do you modify "No Results Found" language in Select2 v4.0

Question

I attempted to use the "language.noMatches" option when initiating Select2 and its throwing an undefined function? How do I go about modifying that bit of text? I would like to include a html button that would add the input from the user if it wasn't found. I tried doing this as a function as well as plain text. I also removed all html to see if that was doing it.

$('#search-select').select2({

   ...

   "language": {
       "noMatches": function(){
           return "No Results Found <a href='#' class='btn btn-danger'>Use it anyway</a>";
       }
   }
});

This was previously "formatNoMatches" in Select2 v3.5

Answer 1

The option noMatches doesn't appear anywhere in the source code.

The actual option is named noResults. The working version of your example is:

$('#search-select').select2({

   ...

   "language": {
       "noResults": function(){
           return "No Results Found <a href='#' class='btn btn-danger'>Use it anyway</a>";
       }
   },
    escapeMarkup: function (markup) {
        return markup;
    }
});

You also need to override escapeMarkup, so the button appears correctly, as per this issue.
