Keep the following points in mind when dragging assets to the asset tray:
When dragging multiple assets to the asset tray, you can add each asset as a separate tile by holding down the CTRL key as you drop the asset.
If the asset tray already contains a tile that represents a group of assets, dragging one or more assets of that same type to the asset tray does not automatically add them to the existing group. Dragging the assets to a blank portion of the asset tray adds them as separate tiles or groups.
To add these assets from the Find or Browse panel to an existing group, drag them to that group’s tile.
To group assets already in the asset tray, select one or more assets and drag them to the group. You can add both individual assets and other groups to a group.
Remember that groups can contain only assets of the same type, such as products or SKUs.
To reorder tiles, drag them to a new location in the asset tray.
To link assets in the asset tray, select one or more tiles, hold down the CTRL key, and drag them to another tile. For example, to link a product to a category, drag the product tile to the category tile, hold down the CTRL key, and drop the product tile.
