Twisties are images used to indicate whether a dropdown or expandspot is collapsed or expanded. Before the release of RoboHelp 8, you had to manually add twisties to your project. This page lists script for adding twisties to your RoboHelp project. They work in all versions of RoboHelp in different output formats.
Show/Hide all links are buttons or links to collapse or expand all dropdowns and expandspot on a page. The twisty script will allow you to add this functionality to your topics. Default RoboHelp twisties are supported.
