有没有其他方法可以编写以下代码而无需使用React.Fragment，因为它无效。
<FormGroup>
<Input type="select" name="selectMultiPrefs" id="MultiPrefs" multiple>
{this.state.arrayForCategs.map(function (CategName, index) {
return (
<React.Fragment key={keyNum++}>
<option key={keyNum++} value={CategName} disabled>{CategName}</option>
{that.props.general.adprefrec.map(function (AdSingle, index) {
<option key={keyNum++} value={AdSingle.prefid}>{AdSingle.name}</option>
})}
</React.Fragment>
)
})}
</Input>
</FormGroup>

这不起作用，因为没有<div class="row">
<?php
/**
* @package Momentum
* Loop custom post type (journal)
* @see https://codex.wordpress.org/Post_Types
*/
/**
* Pagination
* @see https://stackoverflow.com/questions/41738362/how-to-include-pagination-in-a-wordpress-custom-post-type-query
*/
$paged = (get_query_var( 'paged' )) ? get_query_var( 'paged' ) : 1;
$args = array(
'post_type' => 'journal',
'showposts' => 2,
'posts_per_page' => 2,
'order' => 'DESC',
'paged' => $paged,
);
$loop = new WP_Query($args);
if ($loop->have_posts()):
while ($loop->have_posts()) : $loop->the_post();
?>
<div class="col-lg-6 content">
<div class="article">
<div class="image">
<?php
/**

if (has_post_thumbnail()) {
the_post_thumbnail( 'full', array('class' => 'img-responsiv') );
}else { ?>
<img src="<?php echo get_template_directory_uri(); ?>/assets/img/journal-1.jpg" alt="journal">

}
?>
</div>
<div class="text-content">
<div class="head-content">
<div class="title">
<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
</div>
<div class="excerpt">
<?php the_excerpt(); ?>
</div>
</div>
<div class="footer">
<a href="<?php the_permalink(); ?>" class="read-more pull-left">READ ENTRY</a>
<span class="date pull-right"><?php echo get_the_date(); ?></span>
</div>
</div>
</div>
</div><!-- /.col-lg-6 -->
<?php endwhile; ?>
<?php
$total_pages = $loop->max_num_pages;
if ($total_pages > 1) {
$current_page = max(1, get_query_var( 'paged' ));
echo paginate_links( array(
'base' => get_pagenum_link( 1 ) . '%_%',
'format' => 'page/%#%',
'current' => $current_page,
'total' => $total_pages,
'prev_text' => __('PREVIOUS'),
'next_text' => __('NEXT'),

}
?>
<?php else: ?>
<h1>No Journal found</h1>
<?php endif; ?>
<?php wp_reset_postdata(); ?>
</div>这样的东西。
您想使用<Input type="select">。
