Each line consists of some menu text, a link URL (optional), a tooltip title (optional) and a language code or comma-separated list of codes (optional, for displaying the line to users of the specified language only), separated by pipe characters. You can specify a structure using hyphens, and dividers can be used by adding a line of one or more # characters where desired. For example:
