Overview

The Lookup is a widget that allows an end user to search for an item in a collection shown in a drop-down menu.

View Demo

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

HTML
JavaScript
<div id="lookupContainer"></div>
$(function() {
    $("#lookupContainer").dxLookup({
        dataSource: [
            "HD Video Player",
            "SuperHD Video Player",
            "SuperPlasma 50",
            // . . .
        ],
        placeholder: "Select a product..."
    });
});

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 within the inner List widget and in the input field of the Lookup.
JavaScript
var lookupData = [
    { id: 1, country: "Afghanistan" },
    { id: 2, country: "Albania" },
    // . . .
];

$(function() {
    $("#lookupContainer").dxLookup({
        dataSource: lookupData,
        valueExpr: 'id',
        displayExpr: 'country'
    });
});
