prevent click and drag multi selection in fabricjs

Question

How can I disable the click-drag multi selection in fabricjs?

In this image you can see the selection area with a red border:

I want to prevent that kind of selection, but still allow single object selections.

Answer 1

There is a property on fabric.Canvas objects called selection which controls this group-selection behavior.

var canvas = new fabric.Canvas('c', {width: 500, height: 500, selection: false});

//Or quite simply:
canvas.selection = false;
