title: SPFx: How to populate the dropdown with list names
body: <p>I am trying to create a dropdown in the property panel of a webpart with SPFx and I found this tutorial: <a href="https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/guidance/use-cascading-dropdowns-in-web-part-properties" rel="nofollow noreferrer">Use cascading dropdowns in web part properties</a></p>
  
  <p>The problem with the sample is that is is using static data and I would like to know how to fetch the list names dynamically.</p>
  
  <p>How can I do that?
  Best regards
  Americo</p>
