I am using the Flexibility template from Designfromwithin and MODX
I had problems with submenus on touch screens. I discovered the reason for this was that
a href="#" class="flyout-toggle"> (of course with < in front of it) was missing.
After I put this in the outerTpl chunk the submenus functioned, but in the dropdown menus an extra empty field was added. Clicking on it with a mouse showed a page marked as # in a touchscreen the site freezes. Hovering with a mouse over the little triangle also refers to a # page.
On the web I found a code to put the flyout-toggle line in jQuery. I don't know how and where to do this and if it is a solution, for the extra field.

If you need extra information I will be happy to give it. You are able to watch the codes I am using to call Wayfinder etc here: http://forums.modx.com/thread/?thread=18379&page=4
