The input field of the Combobox is being shifted when a "position: absolute" style is set on its initial element.
The input field of the Combobox is shifted when "position: absolute" style is set on its initial element.
When setting "position: absolute" style on ComboBox initial element the whole component should be shifted according to the set "top, bottom, left, right" parameters.
A possible workaround that could be applied in the above linked Dojo is the following one:
$("#comboboxA").getKendoComboBox().input.css("position", "static");
Here is the modified Dojo with correctly working Combobox with "position: absolute" style is set on its initial element.
