Linking internal headers on another column
Per https://docs.google.com/document/d/1jGhIzY6UgLnDsH6Nbb-Q8ioJWVD0L0ml0o59YEuUWco/edit?ts=5a571ce9, we would like to be able to add a side menu like we have in the docs https://docs.gitlab.com/ee/user/project/issue_board.html to all pages instead of the On This Page
section at the top.
@axil mentioned this would take frontend/backend skills. @iamphill could you or someone else on the team assist here/would this be a simple change to implement? cc @jschatz1 @timzallmann
