floating table of contents?

[werkstattcodes]

first of all - many thanks for this elegant hugo theme!
second - apologies if this issue is to trivial. I am only doing my first steps with hugo (as part of R's blogdown package).

I was wondering whether there is any way to include floating table of contents into blog posts. I see from other themes that it's possible (e.g. see here ), however, I have failed to implement it with with your theme.

Before spending more hours of 'trial and error' I wanted to ask whether your theme is in principle able to host such floating table of contensts, or whether this is simply not possible. If possible, I will keep on digging but would of course be grateful for any hint. many thanks.
