By default Help+Manual outputs numbered and bulleted lists with <span> tags formatted as inline-block in HTML-based output formats (HTML Help, WebHelp, Windows Exe and ePUB eBooks, Visual Studio Help). This generally produces better results across all browsers than the standard <ul> and <ol> lists generated when you turn the Export lists as texts option off in HTML Export Options (see below).
Even HTML Help/CHM, which uses Internet Explorer for HTML rendering, will frequently produce unsatisfactory list formatting if you do not use this option. This applies particularly to more complex lists and the indents used in lists.
Bullets are not specified explicitly in list format (UL)
Since the kind of bullets you can use with <ul> tags is very limited, H+M doesn't even bother to specify them, and it does not use graphics as bullets. It just writes an unnumbered list and lets the browser display it. In the default "export lists as text" mode the bullets are defined specifically and the HTML page will look as close as possible to the list in the editor. There are some limitations in Webhelp, as there is no corresponding Unicode symbol for all the possible bullets, but most bullets should work fine.
List formatting is largely under browser control
Help+Manual sets the list indents and basic bullet or number position in list format lists (UL and OL) but it does not try to compensate for differences in the ways that individual browsers manage lists. If you see differences in different browsers this is due to the browsers rendering of the HTML list code, not anything that Help+Manual is doing.
If you want you can configure your project to output lists as standard HTML <OL> and <UL> tags with <LI> list elements. This will produce less attractive formatting and layout in many cases and the appearance will vary greatly from browser to browser. However, it may be necessary for some applications.
•Go to Configuration > Publishing Options > WebHelp/HTML Help > HTML Export Options and deselect the option Export lists as text.
Note that there are separate HTML Export Options settings in the WebHelp and HTML Help configuration sections. The settings in the HTML Help section are used for HTML Help/CHM and the two Microsoft Visual Studio Help formats. The settings in the WebHelp section are used for WebHelp and eBooks (ePUB, Kindle and EWriter).
