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. Suppose, if no matches found then, AutoComplete doesn’t suggest any item.
In the below sample, showcase that how to work autofill with AutoComplete.
let searchData = [
{ 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 = new ej.dropdowns.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');<!DOCTYPE html><html lang="en"><head>

In the following example, filtering is done based on text and value fields.
let searchData = [
{ Name: 'Australia', Code: 'AU' },
{ Name: 'Bermuda', Code: 'BM' },
{ Name: 'Canada', Code: 'CA' },
{ Name: 'Cameroon', Code: 'CM' },
{ Name: 'Denmark', Code: 'DK' },

{ 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 = new ej.dropdowns.AutoComplete({
// bind the country data to dataSource property
dataSource: searchData,
// maps the appropriate column to fields property
fields: { value: "Code", text:"Name" },
//set the placeholder to AutoComplete input
//set item template
itemTemplate:"<span><span class='name'>${Name}</span>-<span class ='code'>${Code}</span></span>",
filtering: function(e)
{
e.preventDefaultAction=true;
var predicate = new Predicate('Name', 'contains', e.text);
predicate = predicate.or('Code', 'contains', e.text);
var query = new Query();
//frame the query based on search string with filter type.
query = (e.text != "") ? query.where(predicate) : query;
//pass the filter data source, filter query to updateData method.
e.updateData(this.dataSource, query);
}
