Grouping Objects

1. Select the objects. You can select multiple objects at once by clicking and holding the left mouse button and then dragging the mouse over the objects to create a bounding rectangle as shown below.
2. Go to the Image Menu and then click Group. 

Alternatively, you can select the objects, right-click anywhere on the Canvas to open the Context Menu and then click on Group like as shown below. 

It's important to note that irrespective of the type of the selected objects, grouping is available for any combination of selected objects(Image, Shape and Text).
