Add data- attribute to time_select element?

[jaredlt]

Hi, is it possible to add a data attribute to the time_select element?

Eg. <select data-input="true">

I have tried the following but it doesn't seem to work:

<%= form.time_select :time_start, 
  combined: true, 
  minute_interval: 30, 
  ampm: true, 
  time_separator: "", 
  end_hour: 23, 
  include_blank: true, 
  data: { input: "true" } # tried adding at the end here
%>

Ah, I was not clarifying the options vs html_options 🤦‍♂️

Ref: https://www.rubydoc.info/gems/actionview/ActionView/Helpers/DateTimeSelector

#initialize(datetime, options = {}, html_options = {})

For future users, the correct format is:

<%= form.time_select :time_start, # :time_start here is the datetime object
  {
    combined: true, 
    minute_interval: 30, 
    ampm: true, 
    time_separator: "", 
    end_hour: 23, 
    include_blank: true
  }, # options
  {  
    data: { input: "true" }
  } # html_options
%>

@jaredlt 👍 that's caught me several times. We can update the readme to include an example for anyone else who is looking for that too.
