Hi
Currently MATLAB does not provide a direct way to disable individual dropdown items.
You can try an alternative workaround as shown below:
  • Add the style to the drop-down component item to change its background color to grey.
s1 = uistyle("BackgroundColor","#808080");
addStyle(app.DropDown,s1,"item",1);
  • Check the selected item in the dropdown's callback function and revert to a previous selection or display a message if a "disabled" item is selected.
Note: This workaround does not make the the option unclickable.
