      y.value = y;
    }
    const onResize = (x,y, width, height) => {
      x.value = x;

<DynoItem class-name-draggable="my-draggable-class">

classNameHandle

Type: String

Used to set the custom common class of each handle element. This way you can style each handle individually using the selector <your class>-<handle code>, where handle code identifies one of the handles provided by the handle prop.

So for example, this component:

<DynoItem class-name-handle="my-handle-class"></DynoItem>

renders the following:

<div ...>
  <div class="my-handle-class my-handle-class-tl"></div>
  <div class="my-handle-class my-handle-class-tm"></div>
  <div class="my-handle-class my-handle-class-tr"></div>
  [...]
</div>

scale

Type: Number|Array
Required: false
Default: 1

The scale prop controls the scale property when the CSS 3 scale transformation is applied to one of the parent elements. If not provided the default value is 1.

<DynoItem :scale="[0.5, 0.4]">

disableUserSelect

enableNativeDrag

<DynoItem :enable-native-drag="true">

active

Type: Boolean
Required: false
Default: false
