Omni Systems, Inc. Mif2Go User's Guide, Version 55
> 20 Providing navigation in HTML > 20.2 Generating trails of links > 20.2.1 Understanding trails of links
A trail of links, often called a “breadcrumb trail”, typically looks something like this:
Home & Garden > Kitchen > Small appliances > Coffee makers
The trail does not necessarily consist of links someone followed to reach a given page; instead, it represents the hierarchical position of the page in the structure of the HTML document.
Each heading in your FrameMaker document that has subheadings can be used as
a link in a trail leading to successively lower subheadings. For each
trail of links Mif2Go inserts the current value of predefined macro
<$_trail>
, which consists of the
following:
Except for the very last item, a trail of links can include only headings at which file splits occur; see §18.2 Splitting files.
Trails of links are not compatible with [HTMLOptions]SmartSplit
(see §18.2.2.3 Preventing splits that leave dangling headings).
If you set SmartSplit=Yes
, wherever a heading
level is missing the previous heading in the trail will be duplicated.
The link will be correct, but the heading text will not.
