Used for single or multiple selection from a set of options.

Basic Usage

label sets the left text content;

columns sets the data source, a one-dimensional array where each option contains value (option value) and label (option name);

v-model sets the value of selected items, data type can be Array | String Number or Boolean;

<wd-select-picker label="Basic Usage" v-model="value" :columns="columns" @change="handleChange"></wd-select-picker>

const columns = ref<Record<string, any>>([{
  value: '101',
  label: 'Men\'s Clothing'
}, {
  value: '102',
  label: 'Luxury Goods'
}, {
  value: '103',
  label: 'Women\'s Clothing'
}])
const value = ref<string[]>(['101'])

function handleChange({ value }) {
  toast.show('Selected ' + value)
}

Type Switch

type defaults to checkbox, when it's the default value, the value type is Array

Set type to radio to enable single selection mode, where value type can be String Number or Boolean.

<wd-select-picker label="Type Switch" v-model="value" :columns="columns" type="radio"></wd-select-picker>

const columns = ref<Record<string, any>>([{
  value: '101',
  label: 'Men\'s Clothing'
}, {
  value: '102',
  label: 'Luxury Goods'
}, {
  value: '103',
  label: 'Women\'s Clothing'
}])
const value = ref<string[]>(['101'])

Disabled

Set the disabled property.

<wd-select-picker label="Disabled" v-model="value" :columns="columns" disabled></wd-select-picker>

Readonly

Set the readonly property.

<wd-select-picker label="Readonly" v-model="value" :columns="columns" readonly></wd-select-picker>

Clearable

Set the clearable property

<wd-select-picker label="Clearable" v-model="value" :columns="columns" clearable></wd-select-picker>

Disabled Options

Each option in columns supports the disabled property.

<wd-select-picker label="Disabled Options" v-model="value" :columns="columns"></wd-select-picker>

const columns = ref<Record<string, any>>([{
  value: '101',
  label: 'Men\'s Clothing',
  disabled: true
}, {
  value: '102',
  label: 'Luxury Goods'
}, {
  value: '103',
  label: 'Women\'s Clothing'
}])
const value = ref<string[]>(['101'])

Display Formatting

Set the display-format property, which is a function type that receives the current selected item (when type is checkbox the parameter is array type, when type is radio the parameter is String Number or Boolean type) and the current options array columns, returns the string to be displayed.

<wd-select-picker label="Display Formatting" v-model="value" :columns="columns" :display-format="displayFormat"></wd-select-picker>

const columns = ref<Record<string, any>>([{
  value: '101',
  label: 'Men\'s Clothing',
  disabled: true
}, {
  value: '102',
  label: 'Luxury Goods'
}, {
  value: '103',
  label: 'Women\'s Clothing'
}])
const value = ref<string[]>(['101'])

const displayFormat = (items, columns) => {
  let showValue = ''
  columns.forEach((column) => {
    items.forEach((item, index) => {
      if (column.value === item) {
        showValue += `${item}: ${column.label} ${index + 1 < items.length ? '--' : ''} `
      }
    })
  })
  return showValue
}

Validation Before Confirmation

Set the before-confirm function, which will be executed when the user clicks the confirm button. It receives value (selected items, which is the currently selected value) and resolve parameters. You can validate the value and use the resolve function to tell the component whether to confirm. resolve accepts 1 boolean value, resolve(true) means the option passes, resolve(false) means the option doesn't pass, and the popup won't close when it doesn't pass.

<wd-select-picker label="Validation Before Confirmation" v-model="value" :columns="columns" :before-confirm="beforeConfirm"></wd-select-picker>

const columns = ref<Record<string, any>>([{
  value: '101',
  label: 'Men\'s Clothing'
}, {
  value: '102',
  label: 'Luxury Goods'
}, {
  value: '103',
  label: 'Women\'s Clothing'
}])
const value = ref<string[]>(['101'])

const beforeConfirm = (value, resolve) => {
  if (value.length > 0) {
    toast.error('Unable to select products at this time')
    resolve(false)
  } else {
    resolve(true)
  }
}
