Hellooo dear community!

I want to create a small dialog box which contains 2 different popup-menu. Do we have any built-in function like that? Or can I change inputdlg's editboxes into popup-menus?

Otherwise I have to create a parent figure which contains Ok, Cancel buttons and two uicontrol objects which are popups. I have to code callbacks for all these and it will be way longer than I expected. That's why I want a short quick solution. Do you have any ideas?

I would argue it isn't that much coding. If you don't use GUIDE it shouldn't take more than 10 minutes to throw something together.

I'll be honest, it took me about 15 minutes, but this should to something similar to what you describe:

selection=doubleDropMenu({'a','b'},{'foo','bar'});
function choices=doubleDropMenu(list1,list2)
%Input a char array or a cellstr, the output is the selection, or 0 when
%the user presses cancel.
f=doubleDropMenu__create_GUI(list1,list2);%create GUI
uiwait(f);%wait for OK or cancel
%retrieve output and close
h=guidata(f);choices=h.choices;close(f);
end
function f=doubleDropMenu__create_GUI(list1,list2)
f=figure('menu','none','Toolbar','none');
h=struct('f',f);
h.button_ok=uicontrol('Parent',f,...
    'Style','pushbutton',...
    'Units','Normalized',...
    'Position',[0.1 0.1 0.3 0.1],...
    'String','OK',...
    'Callback',@doubleDropMenu__Callback);
h.button_cancel=uicontrol('Parent',f,...
    'Style','pushbutton',...
    'Units','Normalized',...
    'Position',[0.6 0.1 0.3 0.1],...
    'String','cancel',...
    'Callback',@doubleDropMenu__Callback);
h.list1=uicontrol('Parent',f,...
    'Style','popupmenu',...
    'Units','Normalized',...
    'Position',[0.1 0.6 0.8 0.2],...
    'String',list1);
h.list2=uicontrol('Parent',f,...
    'Style','popupmenu',...
    'Units','Normalized',...
    'Position',[0.1 0.3 0.8 0.2],...
    'String',list2);
guidata(h.f,h)
end
function doubleDropMenu__Callback(hObject,eventdata)
h=guidata(hObject);
switch hObject
    case h.button_ok
        h.choices=[get(h.list1,'Value') get(h.list2,'Value')];
    case h.button_cancel
        h.choices=[0 0];
end
guidata(h.f,h)
uiresume(h.f)
end

Thanks Rik, actually what I was looking for is a dynamically changing number of popumenus according to inputs I pass to the function. It definetely gave me an idea how to make it.

Thank you for your time and helping me on this :)
