I am using Robert's awesome TOC widget. I want to exclude the "more" tab where your operational layers show up, because they are listed in the TOC widget.
Can I do this in the config.xml?
Assuming your talking about this More tab:
I assume you want to know how to remove it, as it maybe having sync problems with the TOC widget or perhaps you just don't need to show the layers via the More button AND the TOC widget?
I can't take credit for this, but found your answer (untested) in the Esri forums:
Update the Map Switcher Widget's config file.
