I don't know if it's a trend, but I've seen web apps where the layout contains two columns. The left column is approx 20% in width and is the menu. The remaining column is for the content. The menu has rows that you click on and it slides up and down to present the menu options. Sorry, i don't have a screenshot to show you.
Is this look part of a framework that's available in Codeigniter or Zend? Where can i learn more about it?
Thank you for your answers.
