[yinaj60512693]

Hi, I'm using Robohelp 2017 and having a problem adding this expansion button on my generated books and trees

Does anybody know how to add them in the list  and also make them appear when you open .chm file?

The attached figure is the sample of expansion button(submenu) and how i'd like to make my help file with them.

Hi there

When you compile the CHM file, look at the dialog.

Click the Edit button next to Advanced Settings (1)

Then click the TOC Styles tab (2)

Then enable the options for Lines from Root and Plus/Minus Squares (3)

Cheers... Rick
