Creation of Sub NAV

[RDUBPhoto]

In my index file I'm using handlebars to generate the left nav (same as bootstrap) based on the titles of the page. My issue is if I have a section such as "Inputs" I need to have the left nav contain a sub section with Normal, Disabled, Required, etc etc. Is there a way to do this with the current KSS Template file using handlebars? I just need to be able to maybe call out a sub section with a character or something so it knows the difference between a Main header section and the sub level.
