for marker overwrite. One limitation is that fomantic does not have
hover and active effects for the vertical submenu
([reference](https://fomantic-ui.com/collections/menu.html#sub-menu)).
And we might need to overwrite some styles if hover and active effects
are needed.
Update:
Used `data:image/svg` instead of `marker` content. And adjusted styles
for hover effect.
Take admin settings as an example:
