In How to let custom FormBuilder wrap datetime_select's selects in e.g. a div? I basically face the same problem.

JavaScript is not an option for me and the date_separator hack is ... a hack :)

I came up with the following solution (works for me, in HAML). I think it is the cleanest solution so far but relies on some Rails internals.

- date_time_selector = ActionView::Helpers::DateTimeSelector.new(Time.current,
            { prefix: @usage.model_name.param_key,
              field_name: :starttime.to_s,
              include_position: true })
.select
  = date_time_selector.select_year
.select
  = date_time_selector.select_month
.select
  = date_time_selector.select_day
.select
  = date_time_selector.select_hour
.select
  = date_time_selector.select_minute

All you have to do is adjust the prefix (@usage in my case) and the field_name (Attribute-name, @usage.starttime / starttime in my case). In this example, I wrap the corresponding date fields in a div of class "select".

For reference, there are many more options to play with, here are links to the relevant code:
