안녕하세요

KBoard 디스커버 FAQ 스킨 게시판을 사용하는데

리스트 를 클릭했을때 다른 리스트가 닫혀지지 않고 계속 펼쳐져 있어서 

하나가 열리면 다른게 닫혀있게 하고싶습니다.(아코디언)

코드 무엇을 추가해야 할가요 ? 

타이틀부분에 추가해야하는건가요 ? 커스텀 해논 코드 아래 붙여놓겠습니다.

<?php while($content = $list->hasNext()):?>
			<div class="kboard-list-item<?php if($content->uid == kboard_uid()):?> kboard-list-selected<?php endif?>">
				<button type="button" class="kboard-list-button" onclick="kboard_discover_faq_toggle(this)">
					<div class="kboard-list-title">
						<?php if($content->secret):?><img src="<?php echo $skin_path?>/images/icon-lock.png" class="icon-lock" alt="<?php echo __('Secret', 'kboard')?>"><?php endif?>
						<span class="kboard-comments-count"><?php echo $content->getCommentsCount()?></span>
						<span class="accordion"><i class="fas fa-plus"></i></span>
						<td class="kboard-list-mapp"><?php if($content->option->mapp):?><span class="kboard-list-mapp2"><?php echo $content->option->mapp?></span><?php endif?></td>
						<td class="kboard-list-fran"><?php if($content->option->fran):?><span class="kboard-list-fran2"><?php echo $content->option->fran?></span><?php endif?></td>
						<td class="kboard-list-ADD"><?php if($content->option->mapp):?><span class="kboard-list-ADD2"><?php echo $content->option->ADD?></span><?php endif?></td>
						<td class="kboard-list-telll"><?php if($content->option->mapp):?><span class="kboard-list-telll2"><?php echo $content->option->telll?></span><?php endif?></td>
						
					</div>
				</button>
