Dropdown category filter

I don’t see where your posts are pulling from, just the category list, but you are most likely missing the post_count variable where you have your query args to retrieve the posts. post_count=-1 will return all, but it defaults to 10 (or whatever is set in your settings) if you do not specifically say otherwise.
