Hi,
I've created a subtemplate successfully and selected a subtemplate for that category.
But when I create a menu item for the category, subtemplate is ignored and I see Default subtemplate.
Template selection for the menu item also doesnt work and when I save the menu item, it reverts to Default subtemplate.

Please Help, I dont know what to do

Hi. The menu options are only applied when you select more than one category. If you have selected only one category the options in effect are those in the category edit page.

Hi, and thanks for reply
I did this:
I selected a subtemplate in options of category edit page,
Then created a menu item with only one category,
but it still loads Default subtemplate.
