DevExtreme Vue - Overview

The SelectBox widget is an editor that allows an end user to select an item from a drop-down list.

The following code adds the SelectBox to your page. The simplest configuration of the widget requires only a dataSource to be specified. In addition, you can specify the placeholder to be displayed when the SelectBox is empty.

App.vue
  • <template>
  • <DxSelectBox ...
  • :data-source="products"
  • placeholder="Select a product..."
  • />
  • </template>
  •  
  • <script>
  • import 'devextreme/dist/css/dx.common.css';
  • import 'devextreme/dist/css/dx.light.css';
  •  
  • import { DxSelectBox } from 'devextreme-vue/select-box';
  •  
  • export default {
  • components: {
  • DxSelectBox
  • },
  • data() {
  • const products = [
  • "HD Video Player",
  • "SuperHD Video Player",
  • "SuperPlasma 50",
  • // ...
  • ];
  • return {
  • products
  • }
  • }
  • }
  • </script>

If your data is an array of objects, specify:

  • valueExpr
    The data field whose value will be written into the value option.
  • displayExpr
    The data field whose value will be displayed in the drop-down list and in the input field of the widget.
App.vue
  • <template>
  • <DxSelectBox ...
  • :data-source="selectBoxData"
  • display-expr="country"
  • value-expr="id"
  • />
  • </template>
  •  
  • <script>
  • import 'devextreme/dist/css/dx.common.css';
  • import 'devextreme/dist/css/dx.light.css';
  •  
  • import { DxSelectBox } from 'devextreme-vue/select-box';
  •  
  • export default {
  • components: {
  • DxSelectBox
  • },
  • data() {
  • const selectBoxData = [
  • { id: 1, country: "Afghanistan" },
  • { id: 2, country: "Albania" },
  • // ...
  • ];

  • selectBoxData
