Good afternoon,
Some info basic: APEX version 5.03, DB 12c.
Bit of a question and maybe some guidance needed into implementing a feature to similar to what the APEX development team have done in the APEX development environment. I really really like how the have created in top right of the navbar a drop down menu to include buttons, image and some basic information. I have shown this in the picture below (dev enviroment) vs what we get out of the box with APEX 5 in the UT.
Now have the team done all of this with CSS or is there some template options to change and poke around with. It would be a nice benefit to have a drop down very similar in style to this; showing a profile pic and some other information as well as and actual log out button.

Any pointers in the right direction would be great.
Regards
