            Similarly, create split button dropdowns with virtually the same
            markup as single button dropdowns, but with the addition of boolean
            prop <code>split</code> for proper spacing around the dropdown

            We use this extra class to reduce the horizontal
            <code>padding</code> on either side of the caret by 25% and remove
            the <code>margin-left</code> that&#39;s attached for normal button
            dropdowns. Those additional changes hold the caret centered in the
            split button and implement a more properly sized hit area next to
            the main button.
