Hi,

I am developing an application where I need to run some .m files. So, I created a dropdown menu (with 4 options say for eg: a,b,c,d) which when selected and run opens a directory window to select the corresponding .m file to select and run.

If in case in fututre, if the user wants one more option (eg: e) to be added to the dropdown menu list, I have a provision to write the name for dropdown as e and add that to the dropdown menu and run the model.

But, when I close the app and run the app again, the newly added dropdown menu (e) is not there. I need to store that into the database permanetaly. Any suggestions for this ?

   %% Code to add the new dropdown name to the dropdown list      
app.new = app.EditField2.Value;
    if ~any(ismember(app.DropDown.Items,app.new))
        app.DropDown.Items = [app.DropDown.Items app.new];
    end
%% Code to run the corresponding model
if app.DropDown.Value == app.new
    RunModel5; %% name of .m file
end
