Automatic table of contents in Wiki pages

The possibility to create an automatic table of contents in Wiki pages. Currently it is so that the parent wiki page remains empty. You have to manually create a link to each child wiki page that leads to the child wiki page. This is very complicated with many wiki pages. Although there is the navigation bar on the left, it is not very appealing to the users. It would be better if there is an automatic table of contents that links to the subordinate wiki pages. This is clearer for the user and looks better. Alternatively, the navigation bar on the left should always remain.
