A:

According to their live demo's HTML, that widget is is a prettily-styled list. Rather than using javascript, you should be able to click on an element found by css "div.k-widget", then click on an element with css "li.k-item" with the right text inside of it. That's the equivalent to how the user would interact with the device: click on the box, then click on the item they want judging by what the text is. 
Remember: with Selenium, you're usually trying to get as close as possible to how the user will interact with the page, so you can test the user's experience.
