Hi,
i am developping an app in app designer, but i am runing out of space for the drop down list. i wonder if there is a way to make a scrolling dropdown list, just like web pages when you want to go further down you just keep clicking on the rectangle think to the right of the screen.
this is my code :
list = load('Vehiclelist.mat');
assignin('base','list', list);
app.VehicleModelDropDown.Items = list.Vehiclelist;
Vehiclelist = [app.VehicleModelDropDown.Items New_Bat_Name];
save('Vehiclelist.mat','Vehiclelist','-append');
app.VehicleModelDropDown.Items = Vehiclelist;
%% scroll(app.VehicleModelDropDown.Items,1,1); %% << Somewhere here i want to put the
%% scrolling thing
thank you

No, I don't believe that's possible. You could shrink the height so that it only shows 1 item at a time but it will still only show 1 line at a time when scrolling through it.

app.DisplayDropDown.Items = app.Legend_Str; % This is cell 1xn that contains char arrays
This works for me. I believe it appears when the items cannot fit the main window.
You don't have scrolling thing because, most likely you did not load all the data.

+1, yes - once the list gets too long it will automatically add a vertical scoll bar.
