    <p><strong>For WordPress 4.2+</strong></p> <p>Use <a href="https://developer.wordpress.org/reference/functions/wp_script_add_data/" rel="noreferrer"><code>wp_script_add_data</code></a> to wrap the script in a conditional comment:</p> <pre><code>wp_enqueue_script( 'html5shiv', '//cdn.jsdelivr.net/html5shiv/3.7.2/html5shiv.js' ); wp_script_add_data( 'html5shiv', 'conditional', 'lt IE 9' ); wp_enqueue_script( 'respond', get_template_directory_uri() . '/js/respond.min.js' ); wp_script_add_data( 'respond', 'conditional', 'lt IE 9' ); </code></pre> <p>Just make sure you register the script before invoking <code>wp_script_add_data</code> (registering is handled by <code>wp_enqueue_script</code> above), and that the first argument you pass to <code>wp_script_add_data</code> matches the first argument you passed when you registered the script.</p> <hr> <p><strong>For WordPress 4.1</strong></p> <p>You can use the <a href="https://developer.wordpress.org/reference/hooks/script_loader_tag/" rel="noreferrer"><code>script_loader_tag</code> filter</a> today to enqueue scripts wrapped in conditional comments. Here’s an example implementation:</p> <pre><code>wp_enqueue_script( 'html5shiv', '//cdn.jsdelivr.net/html5shiv/3.7.2/html5shiv.js', array(), '3.7.2', false ); add_filter( 'script_loader_tag', function( $tag, $handle ) { if ( $handle === 'html5shiv' ) { $tag = "&lt;!--[if lt IE 9]&gt;$tag&lt;![endif]--&gt;"; } return $tag; }, 10, 2 ); </code></pre> <p>And if you want to include more than one script in the same way, you can use something like:</p> <pre><code>// Conditional polyfills $conditional_scripts = array( 'html5shiv' =&gt; '//cdn.jsdelivr.net/html5shiv/3.7.2/html5shiv.js', 'html5shiv-printshiv' =&gt; '//cdn.jsdelivr.net/html5shiv/3.7.2/html5shiv-printshiv.js', 'respond' =&gt; '//cdn.jsdelivr.net/respond/1.4.2/respond.min.js' ); foreach ( $conditional_scripts as $handle =&gt; $src ) { wp_enqueue_script( $handle, $src, array(), '', false ); } add_filter( 'script_loader_tag', function( $tag, $handle ) use ( $conditional_scripts ) { if ( array_key_exists( $handle, $conditional_scripts ) ) { $tag = "&lt;!--[if lt IE 9]&gt;$tag&lt;![endif]--&gt;"; } return $tag; }, 10, 2 ); </code></pre>

    1. COI found this answer through Google as I was facing the same problem as the OP. It's a great answer, but even the example using an anonymous function isn't that great because you don't properly load the script through Wordpress. Depending on the plugins you use this can lead to issues because perhaps you load the same script twice, so always have an eye at the HTML that Wordpress actually prints.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
