The previous approach doesn't work for DropDownLists because they don't display a cursor like other inputs when focused. By adding a call to jQuery's click method
on top of the focus one, we can make sure that if the first invalid input
is a DropDownList, it will be expanded
for the user to select an option.
I have modified the previous Kendo UI Dojo sample in order to reflect this change; take a look at it here
. Notice how the DropDownList will be expanded if we click the Submit form button when the item selected is --Start Time--
I hope this helps!
