How do i appear Contextual Menu in dhtmlxLayout's cell

hi i use Contextual Menu. but i have one problem. i want to appear this menu at dhxLayout1.cells(“b”).
var dhxLayout;
var dhxLayoutData = {
parent: document.body,
pattern: “3J”,
cells: [
{
id: “a”,
text: “”,
height: “100%”,
width: “250”,
header: false,
collapse: false,
fix_size: [true, null]
}, {
id: “b”,
text: “”,
height: “100%”,
width: “100%”,
header: false
}, {
id: “c”,
text: “”,
height: “233”,
width: “250”,
header: false,
collapse: false,
fix_size: [true, null]
}
]
};
dhxLayout1=dhxLayout.cells(“b”).attachLayout(“2E”);

rightMenu.addContextZone(dhxLayout1.cells(“b”));

Hi,

addContextZone method takes container id as a parameter. Therefore, the following would be more correct:

dhxLayout1.cells(“b”).id = “cellB”;
rightMenu.addContextZone(“cellB”);

it work correct. thank you
