I have the following widgets in the header controller, exactly in this order: layers, buffer, print, measure, legend, base maps and about.
I need to modify the header controller widget so that the Buffer, Print and Measure widgets are in a sub-menu called Operations.
How should I proceed? I tried several ways, even put a div with the fixed menu, but there was no way, because I can not open the widgets if it does this way.
Thanks for any help.
