On the menu, I need to make it keyboard accessible. So user can tab through it. First issue is the dropdown arrows cannot receive focus or have aria-labels. I tried using jquery to fix this but cannot add a tabindex attribute to the span tag. Looks like this can be done via the code but I do not want to make direct changes to the plugin (Styles.php, starting at line 286ish).
Next issue would be to make the menu expand either on focus of the dropdown indicator or onfocus and enter key.
Please let me know if there is a way to do this via your filters or a possible plugin update.
