Thank you Darya but i don’t find any patterns dir and included .js files in the 3.6 package and nothing of this is mentioned in on-line documentation. !
Pattarn’s path:
dhtmlxLayout\codebase\patterns\dhtmlxlayout_pattern4l.js
There is no such thing in documentation, because in 4+ version all the patterns were included in commom layout file and this docs point lost the relevance.
Attaching patternt for you dhtmlxlayout_pattern4l.zip (622 Bytes)
