I have created a very simple dropdown menu where the user will be prompted to choose from the dropdown list. I would like to be able to have a button that will close dropdown menu when the selection has been made.
cityDropdown = uifigure;
citydd = uidropdown(cityDropdown, 'Items', {'Osaka', 'Mumbai', 'Oslo', 'Mombassa'});
city = citydd.Value;
I would like to add a button that says something like "Press here after city selection has been made" that will return the selection to the workspace (line 3), and will close the figure as it's not needed (rather than having to prompt the user to close the figure using the X on the top right corner).
Also, is there a way to add a title?

You need to add a callback function with the 'ValueChangedFcn' property. See the help for the example.
