Recently I had a requirement to create a custom content type. I was no new to this as I had previous such encounters. Post creation of this content type I noticed that the fields were misplaced while creating a node from the same. At first glance it looked a cakewalk shot as we are aware about the default configuration.
Considering the same, I traced to Structure->Content Type->Manage Fields(for my custom content type) to change the order of the fields. Strange to witness, my fields was not present in content type's Manage field page!
