So I’ve got question about how it is possible to configure side categories menu.
As you might notice by the GIF and attached image – right now I only could see the + (plus) mark next to currently opened goods category. Also those square marks at the left are just breaking the logic – they’re not checkboxes, they’re not functional and they does exist.

Questions:
– How it is possible to display pluses next to all categories with subcategories?
– Is it possible to remove squares at the left side?
– Is it possible to make them (squares) functional, as checkboxes?
