Additional Features

• Adding .js-interact-scaled-container to a scaled container around the elements will fix the dragging/resizing issue.

• Passing an onbeforechange option will allow for normalization and validation of the transform before its value updates. This is useful for implementing certain application-specific constraints (e.g. minimum or maximum size).

interact('.constrained', {
  binding: [model, 'transform'],
  resizable: true,

  onbeforechange: function(transform) {
    transform.width = Math.max(100, transform.width); // enforce a minimum width of 100
    return transform;
  }
})
