<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">panel</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for board that I've seen before include "Strip of timber" , "provisioning of meals" , "Go onto (a ship)" , "Supervisory committee" , "Decision-making body" .)
