  Example 1: Static content
  
  My setting outputs : <ul><li>first-blog</li><li>second-blog</li><li>third-blog</li></ul>
  In the end, I have : [BlogDrop,BlogDrop,BlogDrop]
  
  
  Example 2: Dynamic content
  
  My setting outputs : <ul class="metafield-single_line_text_field-array"><li class="metafield-single_line_text_field">first-blog</li></ul>
  In the end, I have : [BlogDrop]
  
  
  Example 3: Empty content (static and dynamic)
  
  My settings outputs : ""
  In the end, I have : "" (which I can easily test with != blank)
