Display parent pages that dropdown to children/grandchildren

Is it possible with your plugin to display categories (or parent pages) that dropdown to then display other pages (children or grandchildren)? The reason is that we don’t want to show all of our pages in a long running list, but do want robots identify all pages via this sitemap page. This feature hides pages within the category (or parent). Here is a nice example https://dandbelite.com/sitemap/

Thanks for the help.
