We can create a Polyline object by creating an instance of fabric.Polyline. A polyline object can be characterised by a set of connected straight-line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity, etc. For ungrouping grouped Polyline objects we can use the toActiveSelection() method. Syntax toActiveSelection(): fabric.ActiveSelection Example 1: Grouping All the Polylines using One Click Before seeing how to ungroup, let's see how we can group objects. In this example, we will have a button on clicking which all the Polylines will ... Read More
