Hello Hammy,
Currently, the Window does not have such docking capabilities, but this is a valid suggestion, so you could log it as a feature request in our Feedback Portal: https://feedback.telerik.com/kendo-jquery-ui/
We will consider implementing it, based on the interest the community shows in it.
Regards,
Ivan Danchev
