How can I present subcategories in the parent category in prestashop?

Question

So, as you can in this image, you can hover over the navigation button "Eliquids", and 4 categories will be displayed in the drop-down list.

All my products are contained in these four categories, however, if you click on the word "Eliquids", it is by itself, it will lead you to a blank page, since all products are stored in the corresponding category.

On the left you can see the categories displayed in the side navigation bar.

How can I make all four subcategories (Chef Blends, steamgunk, etc.) appear in the Eliquids category?

Is this possible through the back office as I cannot find it. Otherwise, is this a source code editing option?

You need to configure the theme-configurator module. On the Customize page, the "Show subcategories" box is displayed at the bottom.
