This is not really optimal a11y wise, mostly because `<a>` elements without a `href-attribute` is not focusable via the keyboard. A more semantically way would be to use a fieldset, legends and buttons:
    `<fieldset>`
        `<legend>`Sort by`</legend>`
        `<button>`alphabetically`</button>`
...
...
 `</fieldset>`
If a screen reader user sets focus on a button it will announce something like "Sort by, alphabetically, button " or "Sort by, sites connected, button"
