 ### Added
 
 - `SplitButton`: `popoverProps` prop which allows overwriting the z-index, direction and height of the popover. ([@lorgan3](https://github.com/lorgan3)) in [#2369](https://github.com/teamleadercrm/ui/pull/2369))
+- `SplitButton`: `processing` prop equivalent to processing on the regular button. ([@lorgan3](https://github.com/lorgan3)) in [#2370](https://github.com/teamleadercrm/ui/pull/2370))
