this._isReadOnly = options.isReadOnly; //specifies whether the control is used for display purposes

            if (!this._isReadOnly) {
                this._editor = $('<div class="cam-taxpicker-editor" contenteditable="true"></div>');
                this._control.empty().append(this._editor).append(this._dlgButton).append(this._hiddenValidated);
                this._control.after(this._suggestionContainer);
            }
            else {

                this._editor = $('<div class="cam-taxpicker-editor" contenteditable="false"></div>');
                this._control.empty().append(this._editor).append(this._hiddenValidated);
            }

 keydown: function (event, args) {
            if (this._isReadOnly) { return false;}
            //get the keynum
            var keynum = event.which;
