在 MATLAB Online 中打开

In the callback for the drop down menu (are you using what the Mathworks badly calls a "popup"?), call uicontrol to create new menu items or controls, or call set() to turn the 'Visible' property of the control to 'on' or 'off'

set(handles.pushbutton1, 'Visible', 'off'); % Hide push button
