Thanks, Alex for the Quick reply.
First of all, there is beautiful and so I wanted to stick to it.
I have just found a workaround solution and I thought that I would post it here if someone else needs such a solution.
Well, in WP editor I added a new category like blogs and made it parent and then added the rest of the 5 categories as kind of subcategories. Blogs is basically a blank category so when I select blogs from the theme, it is obviously showing all 5 categories as these categories are under blogs.
Thank you and keep giving us nice themes.
