@07akioni Could you make menu divider tag with different with menu item tag (div), I want add category text on divider ::before element use tag:nth-of-type(CATEGORY_INDEX), not divider line.😁

I think we won't add it, you'd better using group.

But this way has some problem with sider collapsed, like menu item padding size, item children can not show by hover when sider collapsed, group label can't hide, etc. 😥

I think divider may have problem with sider collapsed. Only submenu supports it.
