title: woocommerce multiple category products display as sequence of category
body: <p>I am working in wordpress wocomerce. I have used shortcode to show three different category product. My shortcode is </p>
  
  <pre><code>[product_category category="5-days-dinner-package,10-days-dinner-package,15-days-dinner-package" columns="3"]
  </code></pre>
  
  <p>Now I want to show <strong>5-days-dinner-package</strong> category product <strong>first</strong> then <strong>10-days-dinner-package</strong> and <strong>15-days-dinner-package</strong> in sequance.</p>
  
  <p>But here I got output as <strong>5-days-dinner-package</strong> then <strong>15-days-dinner-package</strong> and <strong>10-days-dinner-package</strong>.</p>
  
  <p>So what code should I have to write to resolve this problem?</p>
