Your “new-post-writer” only need pick a category, not a page.
Hello jborbely, you might have it sorted out by now. I’m just wanting to share my approach to a similar issue.
Here’s what I’d do in your scenario:
I’d have a ladies fashion page and a gents fashion page. I’d then install for each a navigation bar with a category-based menu. For example, the ladies fashion page menu bar is made of categories of skirts/shoes/etc, the gents’ of categories of tie/shirts/etc.
Menus consisting of categories can be assembled from the dashboard menu function (i’m using WP 2013 theme). Menu bars can be build with some simple coding. (i did it by following some helpful WP forum posts. i’m not trained in coding.)
I believe WP works this way for flexibility for us to arrange and re-arrange ‘content blocks’. Say, one day, your site would like to have the pages based on shoes and fashion accessories instead of on ladies/gents fashion, you only need to change categories for the menu and WP would do the “posts-shuffling” for you.
