3 column layout for k2??

I set the menu to show content in three columns but it is only one long single column. I checked the category and the component. How can this page show in 3 columns?

You display them as latest articles that have special layout. In menu item setting set could for latest articles to 0

here is a screen shot. I have set to 3 columns and to display 9 article in each category but it is one long column.

I think the get the look I am after I will just have to use a module. It seems that the column layout is for multiple categories and I am displaying only one category

So in options for menu item you should have this parameters.

Leading count
Columns for leading

Primary count
Columns for primary

Secondary count
Columns for secondary


simplest:
Leading count = 0
Primary count = 9
Columns for primary = 3
Secondary count = 0
