Hello Suneetha,
You can actually use a RadMenuContentItem to create this type of menu item. You can assign any RadElement based control to the ContentElement property of a RadMenuContentItem. Once doing that, you will simply need to add your newly created RadMenuContentItem to the items collection of the RadSplitButtonElement. Also, as shown in this example, you can add a RadElement based control directly to the items collection of a RadMenu and it will automatically create the RadMenuContentItem for you. This also works when done with the RadSplitButtonElement items collection:
RadCheckBoxElement checkBoxElement = new RadCheckBoxElement();
checkBoxElement.Image = global::MyProject.Properties.Resources.rss_small;
checkBoxElement.Text = "Hello World";
radSplitButtonElement1.Items.Add(checkBoxElement);
