prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  add a select for "subject areas"
  **Describe the feature you'd like and what it will do**
  Currently, subject areas is free text.
  Should be a typeahead -- noninvasive.
  @martinseul suggested that we should populate a list similar to
  https://has.arizona.edu/research-focus-areas
  
  
  Related to https://github.com/hydroshare/hydroshare/issues/4733
