Autoheight for cells
Starting from v7.0, the height of a cell can be automatically adjusted to the height of its content. For that, set the height configuration option to "content":
const layout = new dhx.Layout("layout_container", {
    cols: [
        { 
            header: "Cell header", 
            height: "content" 
        }
    ]
});
