- Adsorption alignment
- Reference line

### Usage

```bash
$ npm install vue3-draggable-resizable
```

```js
// >main.js
import { createApp } from 'vue'
import App from './App.vue'
import Vue3DraggableResizable from 'vue3-draggable-resizable'

```

You can also use it separately within the component

```js
// >component.js
import { defineComponent } from 'vue'
import Vue3DraggableResizable from 'vue3-draggable-resizable'
//default styles
import 'vue3-draggable-resizable/dist/Vue3DraggableResizable.css'

export default defineComponent({
  components: { Vue3DraggableResizable }
  // ...other
})
```

Here is a complete example of using "vue-template"

```vue
<template>
  <div id="app">
    <div class="parent">
      <Vue3DraggableResizable
        :initW="110"
        :initH="120"
