    More information is available in the XUL tutorial.

    Attributes

    acceltext
    Type: string
    Text that appears beside the menu label to indicate the shortcut key (accelerator key) to use to invoke the command. If this value is set, it overrides an assigned key set in the key attribute. This attribute does not apply to menus directly on the menubar.
    accesskey
    Type: character
    This should be set to a character that is used as a shortcut key. This should be one of the characters that appears in the label attribute for the element.

     

    allowevents
    Type: boolean
    If true, events are passed to children of the element. Otherwise, events are passed to the element only.
    autocheck
    Type: boolean
    If this attribute is true or left out, the checked state of the button will be switched each time the button is pressed. If this attribute is false, the checked state must be adjusted manually. When autocheck is true, the button type should be "checkbox" or "radio".
    checked
    Type: boolean
    Indicates whether the element is checked or not.
    Use hasAttribute() to determine whether this attribute is set instead of getAttribute().
    For buttons, the type attribute must be set to checkbox or radio for this attribute to have any effect.

    Note: if the checked attribute is set to true, and you persist its value via the persist attribute, Mozilla will fail to persist its value when the menuitem is unchecked because of bug 15232. A workaround is to set the autocheck attribute to false, then programmatically set the checked attribute when the user selects the item, and set it to false instead of removing the attribute (i.e. do menuitem.setAttribute("checked", "false") instead of menuitem.removeAttribute("checked")) when the user unchecks the menuitem, as a value of false will both correctly hide the checkmark and persist its hidden state.

    command
    Type: id
    Set to the id of a command element that is being observed by the element.
    closemenu
    Type: one of the values below
    Indicates if the menu closes when the menuitem is activated.
    auto
    This, the default value if the closemenu attribute is not specified, closes up the menu and all parent menus.
    single
    The menu the item is contained within is closed, but the parent menus remain open.
    none
    No menus are closed.
    crop
    Type: one of the values below
    If the label of the element is too big to fit in its given space, the text will be cropped on the side specified by the crop attribute. An ellipsis will be used in place of the cropped text. If the box direction is reversed, the cropping is reversed.
    start
    The text will be cropped on its left side in left-to-right text locales, and the right side in right-to-left locales.
    end
    The text will be cropped on its right side in left-to-right text locales, and the right side in right-to-left locales.
    left
    The text will be cropped on its left side.
    right
    The text will be cropped on its right side.
    center
    The text will be cropped in the middle, showing both the start and end of the text normally.
    none
    The text will be not be cropped using an ellipsis. However, the text will simply be cut off if it is too large. The side depends on the CSS text alignment.
    Depending on the platform and theme being used, some elements will have set a maximum width so they will always appear cropped. If you wish to use the value none and the displayed text is larger than this maximum width, you may be able to use the max-width CSS property (or the maxwidth attribute) to override this size. For example, for a menuitem in a menu you can add the following CSS rule when you want to use the value none:
    menupopup > menuitem, menupopup > menu { max-width: none; }
    
    description
    Type: string
    Descriptive text to appear in addition to the dialog title.
    disabled
    Type: boolean
    Indicates whether the element is disabled or not. If this element is set to true the element is disabled. Disabled elements are usually drawn with grayed-out text. If the element is disabled, it does not respond to user actions, it cannot be focused, and the command event will not fire.
    Visible controls have a disabled property which, except for menus and menuitems, is normally preferred to use of the attribute, as it may need to update additional state.
    image
    Type: URI
    The URI of the image to appear on the element. If this attribute is empty or left out, no image appears. The position of the image is determined by the dir and orient attributes.

    Note: The menuitem must have a class of menuitem-iconic for the image to appear.

    key
    Type: id
    Set to the id of a key element whose key shortcut is displayed in the menuitem.
    label
    Type: string
    The label that will appear on the element. If this is left out, no text appears. For an editable menuitem element the value of this attribute is copied to the menulist.value property upon user selection of the menuitem.

     

    name
    Type: string name
    Radio menuitems with the same name as put into a group. Only one menuitem in each radio group can be checked at a time.
    selected
    Type: boolean
    Indicates whether the element is selected or not. This value is read-only. To change the selection, set either the selectedIndex or selectedItem property of the containing element.
    tabindex
    Type: integer
    The tab order of the element. The tab order is the order in which the focus is moved when the user presses the "tab" key. Elements with a higher tabindex are later in the tab sequence.
    type
    Type: one of the values below
    Can be used to create checkable menuitems or for radio button menuitems.
    checkbox
    The menuitem is checked. The checked attribute determines whether the menuitem is checked or not.
    radio
    The menuitem becomes part of a radio group. Other menuitems that have the same value for their name attributes are part of the same radio group. Only one menuitem in the same radio group can be checked at once.

    validate
    Type: one of the values below
    This attribute indicates whether to load the image from the cache or not. This would be useful if the images are stored remotely or you plan on swapping the image frequently. The following values are accepted, or leave out the attribute entirely for default handling:
    always
    The image is always checked to see whether it should be reloaded.
    never
    The image will be loaded from the cache if possible.
    value
    Type: string
    The string attribute allows you to associate a data value with an element. It is not used for any specific purpose, but you can access it with a script for your own use. Be aware, however, that some elements, such as textbox will display the value visually, so in order to merely associate data with an element, you could 1) Use another attribute like "value2" or "data-myAtt" (as in the HTML5 draft), as XUL does not require validation (less future-proof); 2) Use setAttributeNS() to put custom attributes in a non-XUL namespace (serializable and future-proof); 3) Use setUserData() (future-proof and clean, but not easily serializable). For user editable menulist elements, the contents, as visible to the user, are read and set using the Menulist.value syntax. For those elements, setAttribute("value", myValue) and getAttribute("value") do not access or affect the contents displayed to the user.
