Cartan geometry (super, higher)
Let $\pi : P \to X$ be a bundle in the category Diff of smooth manifolds. A vector field $v \in \Gamma(P)$ is vertical with respect to this bundle if it is in the kernel of the derivative $d \pi \colon T P \to T X$.
A differential form on $P$ is a horizontal differential form with respect to $P \to X$ it it vanishes on vertical vector fields.
