I am in the process of designing a website which will be produced in at least 2 phases. The first release will include the majority of the site sections but in phase 2 we will be producing additional functionality.
This means that some sections of the website will only include a single subsection initially but will expand to several subsections at a later date.
My question is: Should I still include a sub-menu for the sections that only have 1 sub-section for now to keep the site consistent and so that the site doesn't appear to restructure itself when we release phase 2, or should the sub-menu be excluded for now and only introduced when there is sufficient content?
I think I'm leaning more toward excluding the menu for now but would value other opinions.
