jQuery UI Dialog maxHeight Option

Last Updated : 12 Jan, 2021

Dialog maxHeight option is used to set the maximum height that can be set to the dialog box. By default, value is false.

Syntax:

$( ".selector" ).dialog({
    maxHeight : 10
});

Approach: First, add jQuery UI scripts needed for your project.

<link href = "https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css" rel = "stylesheet"> <script src = "https://code.jquery.com/jquery-1.10.2.js"></script> <script src = "https://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>

Example 1:

HTML

<!doctype html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <link href=
"https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css"
        rel="stylesheet">

    <script src="https://code.jquery.com/jquery-1.10.2.js"></script>

    <script src="https://code.jquery.com/ui/1.10.4/jquery-ui.js">
    </script>

    <script>
        $(function () {
            $("#gfg").dialog({
                autoOpen: false,
                maxHeight: false
            });
            $("#geeks").click(function () {
                $("#gfg").dialog("open");
            });
        });
    </script>
</head>

<body>
    <div id="gfg" title="GeeksforGeeks">
        Jquery UI| maxHeight dialog option
        Jquery UI| maxHeight dialog option
        Jquery UI| maxHeight dialog option
        Jquery UI| maxHeight dialog option
        Jquery UI| maxHeight dialog option
        Jquery UI| maxHeight dialog option
        Jquery UI| maxHeight dialog option
    </div>

    <button id="geeks">Open Dialog</button>
</body>

</html>
