  <div class="markdown level0 remarks"><p>It's similar to C1ToolbarDropDown but contains two clickable areas.
When clicking on rightmost part with downward-pointing rectangle it
displays popup panel with Content property or context menu set by Menu property.
Clicking on left part of button fires Click event as in the standard button.
Usually the Click event is used to perform default or last action while popup
allows to select alternative options.
<example>
Split button with popup menu.</example></p>
