#### 29.2.2 Specifying whether to include trails of links

To have DITA2Go create trails of links, specify the following setting:

    [Trails]
    ; MakeTrail = No (default) or Yes (enable use of <$_trail>)
    MakeTrail=Yes

The default setting, MakeTrail=No, ensures that the overhead of collecting information to construct trails will not be imposed if you do not use this feature.

When MakeTrail=Yes, DITA2Go creates a trail for any heading (or other paragraph format) for which both of the following are true:

- The format is assigned the [HTMLParaStyles]Trail and Title properties (see §29.2.3 Specifying what to include in trails of links )
- Either of the following is true:
  - The format is assigned the [HTMLParaStyles]Split property (see §27.3.1 Designating split points)
  - [Trails]SplitTrail=Yes (see §29.2.5 Specifying where to display trails of links).

For both split and extracted files, and for the original file, predefined macro <$_trail> causes insertion of a trail according to the settings in [Trails]. The trail is always to the first paragraph in the file. DITA2Go inserts trails only if MakeTrail=Yes.
