Is there any way to open a case that contains left navigation ?
As a following URL, I could open a case that contains left navigation.
When users whose default portal is "UserPortal" open the following URL, it works well and users can open a case that contains left navigation.
But, if users whose default portal is "Developer" open the above URL, it does NOT work well. I opened the attached screen. Is there any way to open a case that contains left navigation ?
