You can manipulate(update or remove) accordion’s arrows, via updating the settings of .smart-arrow CSS class.
To change arrows position in the header you have to update the order, for example order:0 will set the arrow at the beginning of the accordion item’s header block.
If you want to remove the arrow – use display: none ;
To change the arrow with a different icon you have to manipulate it’s ::after pseudo-element.
