If not yet an included feature present...
An option to LEAVE or CLOSE a Dropdown Menu after selection.
After user has selected a page using the ´LEFT 3 lines ICON´ opening a list of a Menu.
I could be interesting to enable an option to :
1) Auto-close the Menu List
2) Re-display only the ´3 Lines ICON´
3) Display the Selected page content below...}
This would force a user to re-click the ´3 Lines ICON´ each time it needs to go to another page...to see the menu...but the Space Gain seems worth this extra work
As for now - The ICON Select Action will Display the Selected page - and above
the full DropDown Menu list - also - remains opened.
You bring up a valid point! I'll bring this up with the team :)
