title: Woocommerce Variable Product, Virtual selected BUT shipping still asked at checkout. Why? How to Disable Shipping?
body: <p>In Woocommerce, I have setup a VARIABLE PRODUCT.
  It contains a few variations.
  Each Variation is ENABLED, ticked as DOWNLOADABLE and VIRTUAL.</p>
  <p>My problem is that even though VIRTUAL is ticked, SHIPPING still appears in the LEFT PRODUCT TABS OPTIONS. This causes Woocommerce CHECKOUT to ask the customer for his shipping info.  I tested it myself, with ordering only this one product, and shipping info is always requested.</p>
  <p>I tried setting up a SIMPLE PRODUCT, and when I tick VIRTUAL the shipping tab disappears from the left options of the product.</p>
  <p>MY QUESTIONS:</p>
  <ul>
  <li>why does ticking VIRTUAL in all VARIATIONS of a VARIABLE PRODUCT not disable SHIPPING TAB like it does for a SIMPLE PRODUCT?</li>
  <li>how can I fix the issue and disable shipping at checkout when a user orders only a VIRTUAL product from a VARIATION?</li>
  </ul>
  <p>thanks for your help!</p>
