HI, Newbie here, I followed a YouTube video explaining how to create sub categories, that worked, but that sub category now displays in my header, I want it to be in the Collections section, otherwise I will end up with a never ending group of subcategories in my header, can anyone offer any help please?
Firstly thank you for taking the time to reply.

If you look along the header there is a link to “Men’s Accessories” there is a drop down there which is just what I wanted to achieve. However, I ideally want it under “All Categories”.
If each time I create sub categories my header will look like a phone directory. 
Any help would be much appreciated.
Thank you
Philip
