썸네일은 아래 코드를 지워주세요.

<div class="kboard-attr-row">
    <label class="attr-name" for="kboard-input-thumbnail"><?php echo __('Thumbnail', 'kboard')?></label>
    <div class="attr-value">
        <?php if($content->thumbnail_file):?><?php echo $content->thumbnail_name?> - <a href="<?php echo $url->getDeleteURLWithAttach($content->uid);?>" onclick="return confirm('<?php echo __('Are you sure you want to delete?', 'kboard')?>');"><?php echo __('Delete file', 'kboard')?></a><?php endif?>
        <input type="file" id="kboard-input-thumbnail" name="thumbnail">
    </div>
</div>

통합검색은

<div class="kboard-attr-row">
    <label class="attr-name" for="kboard-select-wordpress-search"><?php echo __('WP Search', 'kboard')?></label>
    <div class="attr-value">
        <select id="kboard-select-wordpress-search" name="wordpress_search">
            <option value="1"<?php if($content->search == '1'):?> selected<?php endif?>><?php echo __('Public', 'kboard')?></option>
            <option value="2"<?php if($content->search == '2'):?> selected<?php endif?>><?php echo __('Only title (secret document)', 'kboard')?></option>
            <option value="3"<?php if($content->search == '3'):?> selected<?php endif?>><?php echo __('Exclusion', 'kboard')?></option>
        </select>
    </div>
</div>

위 코드 대신 아래 코드를 삽입해주세요.

<input type="hidden" name="wordpress_search" value="3">

화면에 보이지는 않지만 기능은 동작됩니다.
