I import address and click on more options but its don't showing sign Message. It's showing Archive, Transfer, Spend.
Based my thread in my local sub
https://bitcointalk.org/index.php?topic=2946861.0, I'll make this thread more completly with this, especially how to make sign messages bitcoin address at blockchain.info wallet
Question : If there is already a thread about that, why did you created this thread man? Are you wanted to spam or something?! Go away!
Answer : No dear, certainly I'm not. I did this because
Shorena still didn't give detail a tutorial on how to sign a message with new version blockchain wallet.

Just to make clear why I didnt add this to the post.
#1 I just now noticed it and lately I tend to be away from the forum for long periods of time.
#2 I think this tutorial is dangerous or at the very least I have no way to determine how safe it is.[1] It requires you to manually handle private keys and trust (or understand) source code that is not widely used as a wallet. I think the steps could be improved by not relying on the github repo, but rather on e.g. electrum. Then again, importing a key from electrum into bc.i would be pointless as you could just sign with electrum directly.
[1] Is the code sound? Is the entropy generation sound? Are the steps given in a language I dont understand good? Is focus drawn to the possible pitfalls of handling unencrypted private keys in your clipboard? Why this repo and not e.g. bitaddress or brainwallet, etc.?
Edit: I just tested it, addresses created with new wallets still can not be used to sign messages with.
