Customers expect to see your catalog structure at a glance. A long flat list of categories is hard to scan; a tree with nested subcategories that only appear when needed keeps the sidebar clean and still shows the full hierarchy. That’s exactly what a vertical dropdown categories menu does: main categories in a column, and when the visitor hovers over one that has children, a submenu drops in with a smooth animation.

PrestaShop doesn’t ship this behaviour by default. You get a block that either shows everything expanded (noisy) or a static list. Vertical Block Categories fills the gap. The block is built automatically from your real category tree. You don’t edit menu items by hand—you choose which category is the root of the block, how deep the tree goes, whether submenus are animated, and how categories are sorted. The result is a professional, easy-to-use navigation that fits any theme.

On category pages the block can show the current category (or its parent) as the root, so the visitor always sees the relevant branch. On the product page it uses the product’s default category. Optional category thumbnails next to names make the menu even clearer. One module, full control from the Back Office.
