How to enable autofill in EJ2 TypeScript AutoComplete

4 Sep 20264 minutes to read

The AutoComplete supports the autofill behavior with the help of autofill property. Whenever you change the input value, the AutoComplete will autocomplete your data by matching the typed character. If no matches are found, the AutoComplete does not suggest any item.

The following sample demonstrates how to use the autofill property with the AutoComplete.

import { AutoComplete} from '@syncfusion/ej2-dropdowns';

//define the array of complex data
let searchData: { [key: string]: Object; }[] = [
    { Name: 'Australia', Code: 'AU' },
    { Name: 'Bermuda', Code: 'BM' },
    { Name: 'Canada', Code: 'CA' },
    { Name: 'Cameroon', Code: 'CM' },
    { Name: 'Denmark', Code: 'DK' },
    { Name: 'France', Code: 'FR' },
    { Name: 'Finland', Code: 'FI' },
    { Name: 'Germany', Code: 'DE' },
    { Name: 'Greenland', Code: 'GL' },
    { Name: 'Hong Kong', Code: 'HK' },
    { Name: 'India', Code: 'IN' },
    { Name: 'Italy', Code: 'IT' },
    { Name: 'Japan', Code: 'JP' },
    { Name: 'Mexico', Code: 'MX' },
    { Name: 'Norway', Code: 'NO' },
    { Name: 'Poland', Code: 'PL' },
    { Name: 'Switzerland', Code: 'CH' },
    { Name: 'United Kingdom', Code: 'GB' },
    { Name: 'United States', Code: 'US' }];

//initiates the component
let atcObject: AutoComplete = new AutoComplete({
    // bind the country data to dataSource property
    dataSource: searchData,
    // maps the appropriate column to fields property
    fields: { value: "Name" },
    //set the placeholder to AutoComplete input
    placeholder: "Find a country",
     //enable the autofill property to fill a first matched value in input when press a down key
    autofill: true
});
atcObject.appendTo('#atcelement');
