The grid and autocomplete widgets really need no-data templates which display when the returned data is empty. The MVC controls were pretty good at this.

The option to allow new items to be added to the list, as opposed to items exclusively in the datasource.

For example see this: http://jsbin.com/iXEtonO/4/edit, only built in

When using IE10/11, it natively supports the clearing of input element so essentially when hovering over a Kendo ComboBox with a selected value, this is the end result:

I am constantly getting requests to have such way (or adding an extra menu item) to my combo boxes to allow users to click on something and clear the selection. Please consider extending similar functionality to the combo box that is available on all browsers.

There are a couple of things that are very common that I would like to add buttons for.  The first is for clearing the value and the second is a + for adding new items to the list.

The + button is an important one from a usability standpoint.  Quite often the combo/dropdown is populated from a list that is managed on a separate page.  It is too cumbersome to have to use stop entering and go to the admin page to add the new item and then come back to add whatever they were working on previously.

I know I could simply add a button beside the widget but this just doesn't look as nice as it being built in.

Currently it seems that kendoDropDown only supports select elements with options and not optgroups. Would like to see this widget support select elements with both optgroup and option elements.
