Hi Ciaran,
I'm using the Magnolia template. I don't want to use the Header Image(s) under the General Menu in the template, instead I have installed the slideshow module from a recent template purchased and allocated it to slideshow-a position. It works perfectly and I can put text over the slideshow etc.. However my dropdown menu items don't show unless I disable this slideshow module, not sure if they are on the same levels or why it prevents the menu items showing. Any idea please?
