Custom Layout Pattern

Hi,
I’m looking for a pattern that is currently not supported by the additional set of patterns for the Layout. It consists of 2 Columns with the Left column split into 3 windows and the right as is. Similar to the 3J pattern but with an additional window on the left hand side. Could you provide this?
Thanks.

Hi,

it seems that 4G pattern will do. This pattern is not defined in the dhtmlxlayout.js. It requires the corresponding extension from codebase/patterns folder.
