If anyone has unhide developer options by presessing "build number" several times to enable USB debugging and other tweaking and wanting to hide it back... follow the steps below
1. Go to Settings > Apps
2. Swipe left to see ALL
3. Look for "Settings"
4. Select "Settings" (see attached image)
5. Clear data
All done. You do not see "developer options". Any changes that were made under developer options will not be reset (USB debugging will still remain enabled)
Hope it helps.
