Question

I am using Rails and bootstrap4-datetime-picker-rails , and it use Tempus Dominus JS .

I want on hours select, show only hour and after show minutes, without showing the hour and minutes together.

I read the documentation but don't understand if it is possible.

I am using this code:

CoffeScript

$('#datetimepicker14').datetimepicker
  format: 'LT'
  inline: true
  stepping: 5
  disabledTimeIntervals: [[moment({h: 0}), moment({h: 8})], [moment({h: 18 }), moment({h: 24})]]
  disabledHours: [0]

html.erb

<%= f.input :hour, as: :string, as: :hidden, input_html: {id: 'datetimepicker14', data: {toggle: "datetimepicker", target: "#datetimepicker14"}} %>

First show Hours select

Before show Minutes select

Dont show it in the first time, and never show buttons up down
