The default behaviour of select elements is to open up with a space-keypress when the elemented is selected (focused). 

Need to add configuration to display value which is combination of two or more properties or fields in dataSource. Just like valueTemplate in dropdownlist list but without html tags, like

$('#comboboxinput').kendoComboBox({
    dataSource:[{Name:"English (US)", Value:"en-US"}, {{Name:" Japanese (Japan)", Value:"ja-JP"}}],
    template:"<div>#=data.Name+' - '+data.Value#</div>"
    complexValueFormat:"data.Name+' - '+data.Value"
})

I was working on a project where I was asked to display large number of items on dropdown list so i was using template and valueTemplate confugurations, since the items was too large to scroll we decided to use combobox but the problem is unable to display complex values after selecting an item. Currently I'm looping through all items and adding a property DisplayName to each item before setting dataSource. This feature will be very useful and replace dropdownlist if dataSource is too large and complex value is to be displayed.

The problem with relying on maxlength that is built into HTML elements is that they do not work in instances where you are rendering multiple inputs as with the kendo-combo-box. If I set the max length, it sets the max length of the select, which is does nothing. It needs to transfer that maxlength to the input text which is rendered along with the select.

Yes, there are workarounds, but when you are using the controls in an angular mvvm environment where you write little to no jquery, the simplest fix should be to have the control code render the input fully given the information provided.

TLDR:
If given <select kendo-combo-box maxlength="3"
please generate <input class="k-input" type="text" maxlength="3"

A kendoDropDownList places an arrow to the right of the <select/> element, indicating it's a dropdown (.k-i-arrow-s). It would be cool if kendoMultISelect did the same thing. 
Clicking the <select/> element or the arrow should also toggle the visibility on the list items.

Populate selected items when using browser back buttons for both Html and MVC Wrapper versions

On MultiSelect have an option when they type in a complete name and then blur out to save that name.

It works if they hit enter or tab. But if they don't (like if they immediately press the Submit button), then it looks it took their entry but it really did not.

ComboBox and DropDown are different because the first allows you to enter values non in list, but if you are using Cascading ComboBox, entering a value non in list in the first choice, the second choice is disabled. I'like to have cascading for values in list with option for inserting values non in list.

Would be nice to allow selecting items from multiselect several times

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.

The autocomplete inorder to support search and at the bottome display all the results and the number of matched results,
there is need to footer template, like the facebook search autocomplete.

Currently when you enter custom text (referred to as custom value) the control sets the text entered as both the TEXT and VALUE.

I suggest this should operate like the Telerik ASP.NET combobox which only binds custom entered text to TEXT and null as the VALUE.

This then allows you to differentiate between an item selected from the list and one entered.  When you call text() it would return the selected item text or custom text entered and value() would return the selected item data value or NULL if custom text.

the multiselect control should have the possibility to define elements as not editable (readonly) so that those elements can not be removed while other elements can be removed or new elements can be added.

I would love to see the ability to disable/enable items in the DropDownList dynamically at run time.  We have complex validation rules in our UI that need to prevent the user from using certain items if other options are selected.  

The big problem is the DropDownList doesn't let me enable/disable items or add/remove them. 

This means instead of having a few change events wired up to enable/disable items, I need to do it in complex validation rules.

I think the ability to disable/enable items would be a valuable feature to the kendo framework.

I would like to assign multiple values to "dataTextField" property as a part of kendoAutoComplete widget initialization process. This will enable to search and filter values across multiple data fields.

I'd like to add separators between groups of items in a select / kendoDropDownList. Also known as a horizontal line or delimiter.
The same question was asked here by someone else: http://www.telerik.com/forums/separator-in-dropdownlist
The answer was that this is not supported.

Hi guys! I am glad to be back with another feature suggestions for future Kendo UI releases. I am currently working on a project for a client using Kendo UI Multiselect control. The client's pizza ordering system has an interesting feature for selecting double or single portion ingredients. Currently, I'm only able to display the selected items individually, so what it means is that in the selected items, you see 2 of those same items. Perhaps in the future release, can you have some sort of checking to see if there is double entries, and group those into something like "Cheese (x2)". Honestly, this will make Multiselect so much more cooler!! And when the user decides to click on the "X" beside the item with double items, it simply removes one of the selected items by removing the ",id", and then removes the (x2) text. And ofcourse, for better user experience, Kendo UI Multiselect should automatically calculate the number of a single id has been added everytime the user selects the same item.

Adjust KendoDropDownList so that when the mouse scroll wheel does reach the end of the list the focus does not jump out of the control and scroll the form.

If you're trying to create an accessible form, "the value of the for attribute must be the same as the value of the id attribute of the form control" [1]. Since the ComboBox widget generates a new element and hides the original select element, the for attribute no longer matches this new input element. I think it would be good if the ComboBox widget would somehow keep the for attribute of the associated label element in sync with the newly generated input element.

Users wonder why the filter has not been removed from the dropdownlist when they use a browser's text INPUT[X] to delete the filter. The browser raises no event is raised when the X is clicked, and so the list does not revert to the unfiltered list. Users must hit the Delete keys on the keyboard. Although developers can use CSS to remove the browser's [X], it would be more convenient if kendo could do this by default for the dropdownlists's filter box, so that developers would not have to remember to add the CSS every time.

In order to check dirty tracking, I would like to check the defaultSelected of the option of the MultiSelectControl. This now does not work.
