I'm programming a module for day sales management, i mean that it shows details by day >> shifts >> commercials >> Commercial details.

But i have an issue on view which will show those data : because for every day i should show in the same page the related shifts, and also for it i should show the detail of sales by every commercial. (so i have commercials sales details inside shift inside day) about three levels to show.

So i don't know how to present all that in one page, i tried many tabs level but it doesn't work, i don't know if i have something wrong or what ?

Else is there any advanced way to do this job.

I will be thankfull for your guide
