title: Parameter options for User Defined Functions in PowerQuery
body: <p>Hi i have been trying to make a user defined function that allows the user to select the values which the function will use from a list.</p>
  
  <p>I have tried setting the parameter i want as a list to type list in my function but this only seems to accept columns rather than a list of values a user can select from.</p>
  
  <pre><code>let
  ListOfDays = {1.1,0.5,2,3,1},
  DayOfTheWeek = (Day as list, HoursWorked ) =&gt;
   let
      Earnings = Day * HoursWorked
   in
      Earnings
  
  in
  DayOfTheWeek
  
  </code></pre>
  
  <p>What i would like is for me to allow the user to select a single value from the ListOfDays list. I used typed list within my function parameters so that it can give the user a dropdown list kind of option.</p>
