Install and basic usage

``bash
$ npm install --save vue-draggable-resizable
`


Register the component globally

`js
// main.js
import { createApp } from 'vue'
import VueDraggableResizable from 'vue-draggable-resizable'
import App from './App.vue'

createApp(App)
.component("vue-draggable-resizable", VueDraggableResizable)
.mount('#app')
`

You may now use the component in your markup

`vue
// App.vue

`

The component itself does not include any CSS. You'll need to include it separately in your App.vue:

`vue

`html

`

#### classNameHandle
Type: String

Required: false

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

So for example, this component:

`html

`

renders the following:

`html



`

#### 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.

`html



`

#### disableUserSelect

Default: true

By default, the component adds the style declaration 'user-select:none' to itself to prevent text selection during drag. You can disable this behaviour by setting this prop to false.

`html

`

#### enableNativeDrag
Type: Boolean

Required: false

Default: false

By default, the browser's native drag and drop funcionality (usually used for images and some other elements) is disabled, as it may conflict with the one provided by the component. If you need, for whatever reason, to have this functionality back you can set this prop to true.

`html

`

#### active
Type: Boolean

Required: false

Default: false

Determines if the component should be active or not. The prop reacts to changes and also can be used with the syncmodifier to keep the state in sync with the parent. You can use along with the preventDeactivation prop in order to fully control the active behavior from outside the component.

$3

You can style the component using appropriate class names passed as props to the component. Moreover you can replace the default styles for the handles, provided in the source file vue-draggable-resizable.css, but you should take care to define position and size for them. The default classes for handles are handle and handle-tl, handle-br and so on.

The component also provides named slots for each handle, so you can use your markup inside each one.
