Ok, so I found a good example online that does what I want to do.
On Youtube, if you view a video that you own, there's a button
available "EDIT DETAILS" and upon clicking that it makes the Title and
Description Editable text fields.
I'd like to make an update button on a posts page I have and have the
same thing occur, the title and content become text fields which can
then be saved. I just have no idea how to do it though. Any help is
