Wouldn't we all like lists to be seamless. Welcome to the club!
Are you mapping to a CSS file and is it the same one used in all your topics or are you mapping to a Word template?
I think that I may have fixed my problem using a combination of options in the Printed Output snippet from your Web site.
First I applied RH's Style Mapping template to the doc generation and that fixed the formatting of the multilevel lists, but removed other formatting such as headings. But it was easier for me to re-apply all the missing header formatting instead of trying to format the lists, so that's what I did. Then I saved the doc to a template and regenerated the doc again applying the template.
The document is looking good now except for some minor table border issues.
But I do have another question about lists....when I type a list of comments (in normal style) in a topic and then apply bullets or numbers to the list (not multilevel), the words lose the normal style and become (none) style. Is there a way to fix that?
That is the behaviour since RoboHelp 8 and is by design. You can either set up your lists to define the font or you can apply a paragraph style AFTER applying the list style.
You don't have to apply a paragraph style in addition to the list style. Personally I prefer to as it means if I change Normal, my lists will change as well with no further work. That may not suit others so you have to decide which way you want to work.
