Put this in init.vim:

function Multiple_cursors_before()
  let g:deoplete#disable_auto_complete = 1
endfunction
function Multiple_cursors_after()
  let g:deoplete#disable_auto_complete = 0
endfunction

It worked, thanks !

I have added the FAQ.

[wsdjeg]

nice

[husam212]

The solution suggested here is not working for me.

[Shougo]

Please read the documentation.

       function g:Multiple_cursors_before()
         call deoplete#custom#buffer_option('auto_complete', v:false)
       endfunction
       function g:Multiple_cursors_after()
         call deoplete#custom#buffer_option('auto_complete', v:true)
       endfunction

[Shougo]

g:deoplete#disable_auto_complete is old variable.
So it does not work.
