Hello,

I want it so that if let's say 6 posts are posted there automatically comes a new page 2 .

So at the bottom you will have 1, 2, 3 these numbers stand for the pages is this possible? Or do you have to put them all underneath each other?

Many thanks,

Cyberjaap

This is Joomla!'s pagination. You can use CSS to style it in your template to be vertical or horizontal.

Where can I find this options? I can't find it..

the styling is done typically in your Joomla! template.
You might need to ask the template developer about this, since this is template specific.
