Thank you for contacting us.
As far as I understand you are seeking the functionality of RadSplitButton. However, you are not using this control, because you have meet difficulties styling it. If this is the case, I highly recommend you to share your styling issues with RadSplitButton, so that we can assist you. Please note that customizing the appearance of RadSplitButton is times much easier, than overriding the behavior of RadDropDownButton.
