## Vue 3 Support

Vue 3 is supported from `v4.0.0` and beyond (current `master`). To use `vue-simple-context-menu` with Vue 2, use `v3.4.2`.

## Install

```
yarn add vue-simple-context-menu
```

## About

Just a simple little menu to be shown where a click happens - closes after use automatically by clicking an option or outside of the menu. Multiple menus are supported - just make sure to use a unique string as your `element-id` prop value.

A nice feature that comes baked in is the menu placement after a click - it sits just ever so slightly under your click location - so that any hover style you had on the item that was clicked gets removed nicely. I modeled it after the macOS right click menu.

## Usage

```js
import { createApp } from 'vue';
import VueSimpleContextMenu from 'vue-simple-context-menu';
import 'vue-simple-context-menu/dist/vue-simple-context-menu.css';

const app = createApp(App);

app.component('vue-simple-context-menu', VueSimpleContextMenu);
```

```html
<!-- This is a basic use case where you have an array of items that you want
to allow to be clicked. In this case, `items` is an array of objects.
Each item has a click event that ties to a function. See the demo for a full example (with multiple menus as well). -->
<div class="item-wrapper">
  <div
    v-for="item in items"
    @click.prevent.stop="handleClick($event, item)"
    class="item-wrapper__item"
  >
    {{item.name}}
  </div>
</div>

<!-- Make sure you add the `ref` attribute, as that is what gives you the ability
to open the menu. -->
<vue-simple-context-menu
  element-id="myUniqueId"
  :options="options"
  ref="vueSimpleContextMenu"
  @option-clicked="optionClicked"
/>
```

```js
handleClick (event, item) {
  this.$refs.vueSimpleContextMenu.showMenu(event, item)
}


optionClicked (event) {
  window.alert(JSON.stringify(event))
}
```

Note - you must pass the click event-info variable to the `showMenu()` function because that's how we know where to show the menu.

Note - make sure to use `@click.prevent.stop` (or `@contextmenu.prevent.stop` for right click) when setting up the click handler.
