I don't have commenting privileges yet, so couldn't comment on either of these posts (here and here) regarding an entry in a Structure section that links to a Channel index. Between the two posts above I think I mostly understand what's going on, but have a question about an entry type for an entry in a Structure that essentially refers to a page that is a listing of Channel entries (basically an index page for the channel).
My situation: I have an About section with a few subpages that are dropdowns links under "About" in the main navigation bar: Vision, Leadership, and Qualifications. Vision and Qualifications are basically static pages, but the Leadership page lists a number of people (with corresponding images/titles/bios). So, I created a Channel section called "Leadership", each entry containing an individual. In the About section (Structure type) I created two entry types: "about" and "leadership". The "about" entry type has fields such as "body", "hero image", and "subheader" and is used for the static entries Vision and Qualifications. However, for the "leadership" entry type I'm uncertain what fields I should put in it. Since that one entry in the "About" section exists for the purposes of building the navigation, there isn't really any content in that entry. It's just there for the navigation link, and to get the user to a template (in my case templates/about/_types/leadership.html) that will output the individuals from the "Leadership" channel.
Does it make sense that I would just create a "leadership" entry type with no assigned fields (other than the default title), or is there a better way to approach this?
