Is it possible to show subcategories only Part pages / categories?
can you become more specific?
Certainly
I have three main categories
Under each of them have sub-categories
I am interested in category 1 will show the sub category product page
And which does not appear in other categories sub category
When I run the sub categories in
Configuration -> Templates -> Show Children Category
I was shown throughout the site Children Category
But as I would like it to appear only on one page.
There understand?
If i understand well you want the subcategories to be automatically expanded when you are in the product's page or other relevant to categories pages.
Check Custom Filters. It has a good category drop-down which is auto-expanded based on the visited pages
