Even if the Kendo ComboBox does allow free text input, it does not offer support for multiple selection or token mode.
On the other hand, the out-of-the-box the MultiSelect does allow multiple selection and also displays its items in token boxes, but it does not allow free text to be entered and transformed to an item. Nevertheless, the behaviour of the widget could be customized so it allows the user to add a free text entry as a new item in its items collection. Such scenario is implemented on the Add new item Demo
