Adding Syncfusion packages

All the available Essential JS 2 packages are published in npmjs.com registry. You can choose the component that you want to install. For this application, we are going to use AutoComplete component.

npm install @syncfusion/ej2-vue-dropdowns –save

Registering Vue Component

For Registering Vue Component two ways are available. They are as follows.

  • Vue.use()
  • Vue.component()

Using Vue.use()

Import the Component Plugin from the EJ2 Vue Package and register the same using Vue.use() with Component Plugin as its argument.

Refer the code snippet given below.

Copied to clipboard
import { AutoCompletePlugin } from '@syncfusion/ej2-vue-dropdowns';

Vue.use(AutoCompletePlugin);

By Registering Component Plugin in Vue, all child directives are also globally registered.

Using Vue.component()

Import the Component and Component Plugin from EJ2 Vue Package, register the same using the Vue.component() with name of Component from ComponentPlugin and the EJ2 Vue Component as its arguments.

Refer the code snippet given below.

Copied to clipboard
import { AutoCompleteComponent, AutoCompletePlugin } from '@syncfusion/ej2-vue-dropdowns';

Vue.component(AutoCompletePlugin.name, AutoCompleteComponent);

By using Vue.component(), only the EJ2 Vue Component is registered. Child directives needs to be registered separately.

Binding data source

After initialization, populate the AutoComplete with data using the dataSource property. Here, an array of string values is passed to the AutoComplete component.

<div id="app">

  </div>

Vue.use(AutoCompletePlugin);
export default {
  name: 'app',
   data () {
return {
  waterMark : 'e.g. Basketball',
  sportsData: ['American Football', 'Badminton', 'Basketball', 'Cricket',
            'Football', 'Golf', 'Gymnastics',
            'Hockey', 'Rugby', 'Snooker', 'Tennis'
        ]
}
  }
}

return {
  waterMark : 'e.g. Basketball',
  sportsData: ['American Football', 'Badminton', 'Basketball', 'Cricket',
            'Football', 'Golf', 'Gymnastics',
            'Hockey', 'Rugby', 'Snooker', 'Tennis'
        ]
}
  }
}

  #app {
color: #008cff;
height: 40px;
left: 35%;
position: absolute;
top: 35%;
width: 30%;
  }
</style>

Custom values

The AutoComplete allows the user to give input as custom value which is not required to present in predefined set of values. By default, this support is enabled by allowCustom property. The custom value will be sent to post back handler when a form is about to be submitted.

height: 40px;

top: 35%;
width: 30%;
  }
</style>

Configure the suggestion list

By default, suggestion list width automatically adjusts according to the AutoComplete input element’s width, and the height of the suggestion list has ‘300px’. The height and width of the popup list can also be customized using the popupHeight and popupWidth property respectively. In the following sample, suggestion list’s width and height are configured.
