Displaying by default shipping fields on checkout page
<p>On my WooCommerce checkout page, I am selling only one product. The checkout page is showing this product and there is <strong>ckeckbox</strong> next to it, to show the shipping details, when clicked. This is on the default <strong><code>form-checkout.php</code></strong> WooCommerce template. </p>

<p>I would like to have this <strong>ckeckbox</strong> always selected, to  show billing details by default. </p>

<p>I have tried to set:</p>

<pre><code>$checkout = 1;
</code></pre>

<p>With no luck so far. The radio button is displayed by the following hook:</p>

<pre><code>&lt;?php do_action( 'woocommerce_checkout_before_customer_details'); ?&gt;
</code></pre>

<p>Any help letting me know how I can achieve this will be very helpful. </p>

<p>Thanks. </p>
