I have 3 levels in my information architecture for my desktop dashboard. In the vertical navigation which measures H:500px W:200px I have;
- Top level: 8 items
- Second level: 9 items in total (one of my top level item has 7 second levels)
- Third level: 12 items
Would you use an accordion style (which will make the menu long when expanded) or a sequential drill down menu? and why?
