How to create a drop down box with fixed title?

I want a drop box with title 'Math' under which basic mathematical operations will be there-

BasicOperation = uicontrol(parent, 'Style', 'popup', 'Units', 'normalized', 'ToolTipString', 'Add/Subtract', 'String',{' = ',' + ',' - ',' * ',' / '} );

Like in this image - Title 'MATLAB Central' under which some options are there!

Thanks!
