Ok.But my code look like this

parent: document.body, // id/object, parent container for layout
pattern: “3T”, // string, layout’s pattern
offsets: { // optional
top: 10,
right: 10,
bottom: 10,
left: 10
},
cells: [
{
id: “a”, // id of the cell you want to configure
header: true, // hide header on init
text: headerText, // header text
collapsed_text: headerText, // header text for a collapsed cell
height: 147, // cell init height
fix_size: [false, true] // fix cell’s size, [width,height]
},
{
id: “b”, // id of the cell you want to configure
text: “Select/Edit Controls”, // header text
collapsed_text: “Select/Edit Controls”, // header text for a collapsed cell
height: 350,
header: false, // hide header on init
fix_size: [false, false] // fix cell’s size, [width,height]
},

        {
            id: "c",        // id of the cell you want to configure
            text: "Information",     // header text
            collapsed_text: "Information",   // header text for a collapsed cell
            header: true,      // hide header on init
            width: 500,
            fix_size: [true, false] // fix cell's size, [width,height]
        }


    ]

});
pls help me on this

Please, try to attach another 2E layout to the “b” cell of your localizationApp.layout:

your_2e_layout= localizationApp.cells("b").attachLayout("2E");

and attach the the grid and tabbar components to the cells of your 2E layout using the attachGrid() and attachTabbar() methods:
https://docs.dhtmlx.com/layout__attach_components.html

Thanks For the response.It is working Good.
