Solution:

HTML Code:

<!DOCTYPE html><!-- Define document type as HTML -->
<html><!-- Begin HTML document -->
<head><!-- Start of document header -->
<meta charset="utf-8"><!-- Define character encoding -->
<title>How to specify that a drop-down list should be disabled</title><!-- Title of the HTML page -->
</head><!-- End of document header -->
<body><!-- Start of document body -->
<form name="example" action="html-select-option-optgroup-example.html" ><!-- Start of form with name and action attributes -->
Select one or more sections: <!-- Prompt for user selection -->
<select name="languages" autofocus><!-- Start of dropdown menu with name and autofocus attributes -->
<optgroup label="Server_side"><!-- Grouping of options with a label -->
<option>PHP</option><!-- First option under Server_side group -->
<option>ASP</option><!-- Second option under Server_side group -->
<option>Ruby on Rails </option><!-- Third option under Server_side group -->
</optgroup><!-- End of Server_side group -->
<optgroup label="Client_side"><!-- Another grouping of options with a label -->
<option disabled>JavaScript</option><!-- First option under Client_side group, disabled -->
<option disabled >VB Script </option><!-- Second option under Client_side group, disabled -->
</optgroup><!-- End of Client_side group -->
</select><!-- End of dropdown menu -->
</form><!-- End of form -->
</body><!-- End of document body -->
</html><!-- End of HTML document -->

Explanation:

This HTML code defines a webpage with a form containing a dropdown menu.
The form allows users to select one or more sections.
The dropdown menu has two groups: "Server_side" and "Client_side".
Each group contains multiple options.
The <option> tags within the "Client_side" group have the disabled attribute, which prevents users from selecting these options.
By disabling certain options, it's possible to indicate that they are not currently applicable or available for selection, thus controlling user input in the dropdown menu.
