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 label for the element.

 

allowevents
Type: boolean
If true, events are passed to children of the element. Otherwise, events are passed to the element only.
command
Type: id
Set to the id of a command element that is being observed by the element.
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; }
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.
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.

 

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.
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.
