Why updated forge viewer's model browser isolate the items instead of select?

Question

In the older version(7.1.*) of forge viewer the Model browser select the item and focus the selected item.

But in the latest version(7.*.*) it isolate the item(s).

Is there any way or settings to get back to the older functionality in the latest version?

You can change the behavior by specifying options.docStructureConfig on ModelStructurePanel.

Prevent zoom in Forge viewer when clicking in Model Browser

As described in the blog post, you can change the behavior by creating custom ModelStructure Panel on Autodesk.Viewing.OBJECT_TREE_CREATED_EVENT handler or you can specify the option in its constructor.

You also can specify the option in GuiViewer3D constrictor like below.

var options = {
    docStructureConfig: {
        click: {
            onObject: ["selectOnly"] //instead of toggleOverlayedSelection
        },
        clickShift: {
            onObject: ["isolate"] //instead of toggleMultipleOverlayedSelection
        },
        clickCtrl: {
            onObject: ["selectToggle"] //instead of toggleMultipleOverlayedSelection
        }
    }
}
viewer3d = new Autodesk.Viewing.GuiViewer3D(document.getElementById('forgeViewer3d'), options);
