The menuitem tag is a lesser-known but essential HTML element that allows developers to create interactive menus in web applications. As part of the HTML specification, its primary purpose is to define a menu item within a menu or menubar, representing actions that users can perform. In this article, we will explore the details of the menuitem tag, its attributes, examples of how to use it, and related tags. Let’s dive into the world of HTML menus and learn how to enhance our web applications with this functionality.
I. Introduction
A. The menuitem tag is part of the HTML5 specification. It acts as a container for a single command that can be invoked. The tag is particularly useful when creating user interfaces that require menus, such as in web-based applications.
B. The primary purpose of the menuitem tag is to allow developers to define actions that users can execute from a menu. It provides an interactive way for users to engage with the application and carry out specific tasks.
II. Browser Support
A. When working with any HTML element, it’s crucial to consider browser compatibility. Unfortunately, the menuitem tag has limited support across modern browsers, which may affect how it is displayed and utilized in web applications.
B. Below is a table listing the current support status for the menuitem tag among major browsers:
Browser | Support |
---|---|
Chrome | Partial |
Firefox | Partial |
Safari | No |

III. Attributes
Below is a list of attributes that can be used with the menuitem tag to define its behavior and appearance:
Attribute | Description |
---|---|
type | Specifies the type of menu item: “command,” “checkbox,” or “radio.” |
disabled | Disables the menu item, preventing user interaction. |
label | Defines a user-facing label for the menu item. |

<menuitem label="Open" icon="open.png" onclick="openFile();" type="command"></menuitem>
<menuitem label="Settings" icon="settings.png" disabled></menuitem>
</menu>
