I'm trying to link from a one page (nueva zona) and from the childrens of this (nuevo equipo) to another page (nuestras sedes). Both are on the same level. I also want to link to the same site (nuestras sedes) from its parent page (nuevo torneo).
The problem is i can't use template controls such as childrenOf(url) or page(url) because the user is going to be creating these pages dynamically.
It's a bit complicated to explain, better leave the image so that it can be better understand
If you don't need to place them in the template, then the content editor can just add the links in the content of each page. Otherwise you could use something like a has_one to SiteTree, and then a TreeDropdownField to select the page you want to link to.
