Layout needed

I am looking to create a 2 over 2 layout which has 1 vertical and 1 horizontal seperator

basically just 4 squares.

Is there any doc avail to create these custom layouts?

There is not such docs. Here is the demo with available patterns dhtmlx.com/docs/products/dht … terns.html

You may put one layout into a cell of another in order to get the desired layout.
