<template>
    <select2-vue :options="selectOptions" v-model="selectedValue" placeholder="Select an option" />
</template>

<script setup>
import { ref } from 'vue';
import Select2 from 'select2-vue';

const selectedValue = ref(null);
const selectOptions = [
    { id: 1, text: 'Option 1' },
    { id: 2, text: 'Option 2' },
    { id: 3, text: 'Option 3' },
];
</script>

Styles

To ensure proper styling, include the Select2 CSS file in your project:

import 'select2-vue/dist/select2-vue.css';

Props

The select2-vue component accepts the following props for customization:

| Prop | Type | Default | Description | | ------------- | --------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | options | Array | [] | Array of select options. Each option should be an object with id and text properties. | | modelValue | Any | null | The currently selected value (can be bound with v-model). | | placeholder | String | "" | Placeholder text displayed in the select box. | | multiple | Boolean | false | Enables multiple selection. | | disabled | Boolean | false | Disables the select box. | | config | Object | {} | Custom settings to pass directly to the underlying Select2 instance. See Select2 documentation for available options. |

Events

The component emits several useful events for better control over the Select2 instance:

| Event | Description | | ------------------ | ----------------------------------------------------------------------------------- | | select2:select | Fired when an option is selected. The selected item is passed as the event payload. | | select2:unselect | Fired when an option is deselected (in multiple mode). | | select2:opening | Triggered when the dropdown is about to open. | | select2:closing | Triggered when the dropdown is about to close. | | change | Fired when the value changes, passing the new value. |

Example:

<template>
    <select2-vue
        :options="selectOptions"
        v-model="selectedValue"
        @select2:select="handleSelect"
        @select2:unselect="handleUnselect"
    />
</template>

<script setup>
import { ref } from 'vue';

const selectedValue = ref(null);
const selectOptions = [
    { id: 1, text: 'Option 1' },
    { id: 2, text: 'Option 2' },
    { id: 3, text: 'Option 3' },
];

function handleSelect(selected) {
    console.log('Option selected:', selected);
}

function handleUnselect(unselected) {
    console.log('Option unselected:', unselected);
}
</script>

Example: Using Remote Data

You can fetch data dynamically from a remote API using the ajax option:

<template>
    <select2-vue :settings="select2Settings" v-model="selectedValue" />
</template>

<script setup>
import { ref } from 'vue';

const selectedValue = ref(null);
const select2Settings = {
    ajax: {
        url: 'https://api.example.com/data',
        dataType: 'json',
        processResults: function (data) {
            return {
                results: data.items.map((item) => ({
                    id: item.id,
                    text: item.name,
                })),
            };
        },
    },
};
</script>

Example: Multiple Selection with Tagging

Here’s an example where you can add new tags or select multiple values:

<template>
    <select2-vue :settings="select2Settings" v-model="selectedTags" placeholder="Select or add tags" />
</template>

<script setup>
import { ref } from 'vue';

const selectedTags = ref([]);
const select2Settings = {
    tags: true,
    tokenSeparators: [',', ' '],
};
</script>
