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" },
- // ...
- ];
- return {
- selectBoxData
- }
- }
