Nest subcategories under their parent categories in the sidebar

[dax (Daniela)]

Open your dev console and take a look to the data-list-item-name record:

Then you can target them in your CSS, e.g.

li.sidebar-section-link-wrapper {
  &[data-list-item-name="New"], 
  &[data-list-item-name="Global leaderboard"], 
  &[data-list-item-name="Test leaderboard"] {
    margin-left: 1em;
  }
}

With a similar approach you can move a whole section instead of single links:

.sidebar-section-wrapper.sidebar-section[data-section-name="new-global-links-section"] {
    margin-left: 1em;
}
