How can I group and ungroup layers in a design?
Group – To group layers, select SHIFT (bulk) or CTRL (individual) and select the layers you want. Next, right click on one of the selected layers and select Group Layers. The layers will be grouped into a folder. You can then rename the folder in the layers panel, by double clicking on Group.
Ungroup – *Before ungrouping layers, make sure the folder is not locked. To ungroup a folder, select it first, then right click on the folder icon and choose Ungroup Layers.
