Problem with views

[eluser]invi[/eluser]
Hello everyone!

Up to this moment I have always found solutions for my problems in archived topics.

I have a template of my new application which consists of header, content divided into 3 columns [left, main, right] and footer. In the left column there is always login form [div block] but it should only be shown when user is not logged in. After logging there should be shown user menu. I do not know how to organize my views in this case. I was looking for solutions but I didn't find anything suitable for me.

Please help me to deal with this problem because I am new to CI and MVC in general and not everything is clear for me yet.
