I have been using this example to test a jQuery autocomplete textbox, which works fine.
The problem is the suggestion list only popup when I write something on the textbox. When the textbox become empty then popup list is also become invisible. But I need it to work like this, when the textbox is empty and cursor focus on the textbox then all suggestion entry or top 10 entry will be visible on the autocomplete textbox.

Thanks in advance, your help is greatly appreciated.

Hi,

If you check out the api documentation[^] for the autocomplete widget, it explains how to use the minLength option.

If you set the minLength option to zero, then the suggestion list should be displayed.

[quote]
The minimum number of characters a user must type before a search is performed. Zero is useful for local data with just a few items, but a higher value should be used when a single character search could match a few thousand items.

... updated to add updated usage example (based on the jQuery example[^]):

JavaScript

<script>
$(function() {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme"
];
$( "#tags" ).autocomplete({
source: availableTags,
minLength: 0
});
});
</script>
</head>
<body>

<label for="tags">Tags: </label>
<input id="tags">

... hope it helps.
