Mini TOC in HTML 5 Help Frame 2017

FR book

Use Mini-Tocs in many chapters

the format in the PDF files uses the numbering and on page

i.e each item says

3.2 Installation    on page 7

etc

In the HTML 5 Help i want only the topics to appear without the numbering and page numbers

How can this be done

1. possibility - change the style in reference page and use a different template in Help - did not manage to make this work

2. I found reference on the internet to using an HTML template - I tried this, but did not see how to make it work

All insights/hints and tips will be welcome
