jQuery Tagsinput v0.8.0
The tags closely resemble the labels and follow the same line of color. To use them, you need to use the default class
                    .tagsinput, and add a variation at line 11 of
                    bootstrap-tagsinput.js and change the class
                    badge-danger with the color that you want:
                    badge-info | badge-success | badge-warning | badge-primary
                
tagClass: function(item) {
  return 'badge badge-danger';
