Skicky menu in column

# Support

## Description

Does bootstrap_package have a built-in function for sticky elements in a column (e.g. a sub-navigation in the right colums)?
How can I activate this behaviour?

The issue concerns bootstrap_package and links to Bootstrap's navbar documentation; start by checking whether the package provides built-in sticky behavior for a right-column sub-navigation. Done means confirming whether the behavior exists and documenting the activation steps, or clearly stating that it is unsupported.
