How to make floating ladders
I need to know how I can make floating ladders in Minceraft, preferably without Single Player Commands, like the below picture in survival singleplayer. I have MCEdit if this can be done in MCEdit.
Thank you for any helpful information.

You can add invisible "barriers" and put ladders on them. See this link for more information about them.
It needs at least version 1.8 in order to work.
To get some barriers:
/give @p minecraft:barrier 64
@p stands for the nearest player (which is always you, Note: not in command blocks) and 64 stands for amount.
Also it says,
All dependent blocks can be placed on a barrier, such as trapdoors or redstone.
and
Barriers are transparent to light.
So you can make somethink look like this all the time, not sure that solid blocks are what you want, but I hope I helped you.

Put barrier's on the back of the ladders
To get barrier's in PE write this command, /give @p barrier
To get barrier's in Java write this command, /give @p minecraft:barrier
Barrier's are invisible blocks. When barrier held in hand you can see all the barrier's you put but when it is not in your hand they are just plain invisible solid blocks
