it is recommended to give different class names: 

<div class="theme-options">
 <div class="cart-title"></div>
   <ul>                                               
    <li class="sku-line selected sel-flavor" data-id="1"></li>
    <li class="sku-line sel-flavor"  data-id="2"></li>
    <li class="sku-line sel-flavor"  data-id="3"></li>
   </ul>
 </div>
<div class="theme-options">
   <div class="cart-title"></div>
      <ul id="test">
       <li class="sku-line selected sel-pack" data-id="1"><i></i></li>
       <li class="sku-line sel-pack" data-id="2"><i></i></li>
       <li class="sku-line sel-pack" data-id="3"><i></i></li>
       </ul>
     </div>

then when you click the "add Shopping cart" button: 

$("-sharpLikBasket").click(function(){
   console.log($(".sel-flavor.selected").data("id"))//data-id
   console.log($(".sel-pack.selected").data("id"))//data-id
})

add that id should not be repeated on the same page. 

id="taste" //liidid

if there is a reference to jQuery: 

$('.sku-line').on('click', function() {
    var id = $(this).data('id');
    console.log(id);
})

.
this question is very simple.

generally similar problems can be solved in the same way,

your selection does not turn red, it should contain some class

Click to add the shopping cart traversal element to see if there is a class.

the second method,

set a variable in js, initially null

Click on an element to get the data-id assignment to the variable.
Click the add Shopping cart button to get it.
