Sort messages per category on a different page

With that link I’m able to add the text I want on top of a category when people view a certain category. But it does not solve the split I want on the homepage.

I’d like to have the categories in my main navigation. So if they click BLOGS they will only see the blogs (and the text I’d like to show on the top of the page). And if they click on COLUMNS, they only see the messages I linked to category ‘columns’.

So what will you be showing on your site’s home page?

I’ve made the homepage a static one with a short text.
Then I want to pages. One for Blogs, one for Columns.

In settings I’ve appointed the messages to be shown on the Blog page but I also want messages on the Column page. And split them by category.

You would need to add a custom query to your theme’s index.php page to exclude posts from the Columns category.

With this I can exclude the COLUMNS frog the blog page but how do I create en COLUMS page where I can exclude the BLOGS. In the settingsmenu I can only appoint 1 page to show the messages.

The COLUMN category page will only show the COLUMN posts.

This script only excludes the COLUMNS from the BLOG page am I right?
So how do I get a COLUMN page in the main menu, only showing COLUMNS
