iPhone ,iPad ,Sidebar Bookmark Display Removed

Fixing The Sidebar Or Bookmark Feature Display On Your iPhone: Okay so I came across an issue with my iPhone the other day and couldn't come up with an answer after searching online for several days to find one. When I would switch to side view on my iPhone 6 while searching the bookmark sidebar would show up taking up nearly half my search screen view which I didn't want,so I began to search my phone for a way to remove this which didn't happen until I looked above at the top where the icons were and there it was this book icon which once activated or pressed has a blue color around it to bring up the bookmark sidebar,then if pressed again removes the blue indicator and bam,no more sidebar. Hopefully this will help someone else as well.
