richlistitem

An individual item in a richlistbox.

(example needed)

disabled: Type: boolean; Indicates whether the element is disabled or not. If this attribute is set, 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. In the case of form elements, it will not be submitted. Do not set the attribute to true, as this will suggest you can set it to false to enable the element again, which is not the case.
The disabled attribute is allowed only for form controls. Using it with an anchor tag (an <a> link) will have no effect.

The element will, however, still respond to mouse events. To enable the element, leave this attribute out entirely.; 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.

searchlabel: Type: string; Text used for 'find-as-you-type' (FAYT) searching. In situations where the search text is ambiguous or missing, searchlabel can be used to give context to FAYT. If searchlabel is not present, FAYT falls back to use the label property.

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.; Note that in multiprocess Firefox, this attribute means only that the user (or code) has initiated tab selection, not that the browser has actually switched to the tab. If your code needs to apply some styling to the currently selected tab, you should use the visuallyselected attribute, which is available from Firefox 40 onwards. See tab selection in multiprocess Firefox for more details.

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.

accessible: Type: nsIAccessible; Returns the accessibility object for the element.

control: Type: element id; Gets and sets the value of the control attribute.

disabled: Type: boolean; Gets and sets the value of the disabled attribute.

label: Type: string; Gets the concatentation of text from any child label elements. Does not support setting label values. Use the child elements directly to set label text.

searchLabel: Type: string; Gets and sets the value of the searchlabel attribute.

selected: Type: boolean; This property's value is true if this element is selected, or false if it is not. This property is read only. This property is available for menuitem and menuseparator elements in Firefox 3.

tabIndex: Type: integer; Gets and sets the value of the tabindex attribute.

value: Type: string; Gets and sets the value of the value attribute. For textbox and user editable menulist elements, the contents, as visible to the user, are read and set using the Textbox.value and Menulist.value syntax.
