How to update the source Option in bootstrap-typeahead.js

Question

I am using bootstrap-typeahead in order to allow multiple selection. Here is the demo.

The original code has been update by @Sherbrow Twitter bootstrap typeahead

Answer 1

Based on the default updater method of typeahead :

updater: function (item) {
  var pos = this.source.indexOf(item);
  if(pos != -1) {
    var newSource =
      this.source.slice(0,pos)
      .concat(this.source.slice(pos+1));
    this.source = newSource;
  }
  return item
}

Demo with multiple values (jsfiddle)

Keep in mind that you can access this source from anywhere with $('sel').data('typeahead').source considering that the typeahead is initialized
