Row within row

Hi,

I need to know if is possible to add a new row inside an existing row.

If I write this:

[efsrow]
   [efscolumns large-xx]
      [efsrow]
         /* others shortcode */
      [/efsrow]
   [/efscolumns]
[/efsrow]

the shortcode structure breakdown and the

[/efscolumns]
[/efsrow]

is displayed like simple text by wordpress.

How to fix it? I need to create a complex grid structure.

Thanks
