 * Hi,
 * When running my site through [https://validator.w3.org/nu/](https://validator.w3.org/nu/)
   I noticed an error to do with duplicate tabindexes. The error happens with this
   plugin, here is an example of the code:
 * ul role=”radiogroup” aria-label=”Prescription Interval” class=”variable-items-
   wrapper button-variable-items-wrapper wvs-style-squared” data-attribute_name=”
   attribute_prescription-interval” data-attribute_values=”["1 month",&
   quot;3 months&quot;,&quot;6 months&quot;,&quot;12 months&quot;]”><li aria-checked
   =”false” tabindex=”0″ data-wvstooltip=”1 month” class=”variable-item button-variable-
   item button-variable-item-1-month ” title=”1 month” data-title=”1 month” data-
   value=”1 month” role=”radio” tabindex=”0″><div class=”variable-item-contents”
   ><span class=”variable-item-span variable-item-span-button”>1 month</span></div
   ></li><li aria-checked=”false” tabindex=”0″ data-wvstooltip=”3 months” class=”
   variable-item button-variable-item button-variable-item-3-months ” title=”3 months”
   data-title=”3 months” data-value=”3 months” role=”radio” tabindex=”0″><div class
   =”variable-item-contents”><span class=”variable-item-span variable-item-span-
   button”>3 months</span></div></li><li aria-checked=”false” tabindex=”0″ data-
   wvstooltip=”6 months” class=”variable-item button-variable-item button-variable-
   item-6-months ” title=”6 months” data-title=”6 months” data-value=”6 months” 
   role=”radio” tabindex=”0″><div class=”variable-item-contents”><span class=”variable-
   item-span variable-item-span-button”>6 months</span></div></li><li aria-checked
   =”false” tabindex=”0″ data-wvstooltip=”12 months” class=”variable-item button-
   variable-item button-variable-item-12-months ” title=”12 months” data-title=”
   12 months” data-value=”12 months” role=”radio” tabindex=”0″><div class=”variable-
   item-contents”><span class=”variable-item-span variable-item-span-button”>12 
   months</span></div></li></ul>
 * As you can see, every <li> element has tabindex=”0″ twice.
 * The relevant code is in includes/class-woo-variation-swatches-product-page.php
   around line 370.
 * It is quite a minor issue, but I think HTML errors somewhat affect pagespeed 
   scoring (I think, in any case our client would prefer to have no HTML validation
   errors).
 * Thanks!

 * Thanks for reaching out to us. Can you please share which Variation Swatches 
   version you are using on your site?
 * Please make sure you have added any js to push “tabindex” to `<li>` or not. Also,
   you can plugin conflict test by disabling all plugins except WooCommerce and 
   Variation Swatches.
 * To run the plugin conflict test, you can use Health Check & Troubleshooting plugin.
 * From my inspection, I didn’t find a second tabindex. You can check this URL:
