The page http://docs.kendoui.com/getting-started/web/combobox/cascading has some great FAQ.

One entry is related to work I am doing:
"Q: I am using comboboxes with load on demand (autoBind: false) and I need to pre-set the selected items."

However, the question I have is to related multiple cascades

$("#level1").kendoDropDownList ({ ... });
$("#level2").kendoDropDownList ({ ... cascadeFrom: "level1" ...});
$("#level3").kendoDropDownList ({ ... cascadeFrom: "level2" ...});

Is there a fiddle or example show cascadeFrom working with 2 or more linkages ?
Is the cascading system developed to handle multi-level cascades in the proper serial manner so as to arrive at the states of the following four actions?

Action
1.
level1 optionLabel selected
-> level2 & 3 disabled & emptied,
-> level2 & 3 optionLabel displayed

2.
level1 selected
-> level2 queried using level1
-> level3 disabled & emptied
-> level2 & 3 optionLabel displayed

3.
level2 optionLabel selected
-> level3 disabled & emptied
-> level3 optionLabel displayed

4.
level2 selected
 -> level3 queried using level2
-> level3 optionLabel selected

Thanks,
Richard

Hello Richard,

 
The cascading functionality works has the required behavior. You can find more information about it here.
Check this jsFiddle demo too.
