Sales Item Event - Create - Select specific intervals for event

As a store manager I want to be able to select any 15 minute interval within a day for my sales item event so that I can configure the event to match when I anticipate it will occur

Notes

• Sales Item Events will be entered in 3 steps
  1. Select: date, name and type (sales item event)
  2. Select the intervals/time periods
  3. Select the Sales Items and enter the adjustments

• This story is to capture the new interval/time period selection page
• The Select Time Period(s) page is similar in behavior to the page used to configure Manual Adjustments
• The differences:
  • The Manager Adjustment (%) column is replaced with a checkbox
  • The Actions button is replaced with Select Sales Item(s)
• Mockup
• 

Acceptance Criteria

1. The checkbox column is used to indicate that intervals should be used in the Sales Item Event
2. Selection cascades down, for example:
   • Select Day Totals - All intervals are included
   • Select Breakfast ( 5:00 AM - 10:30 AM ) - All intervals within the breakfast day part are selected
   • Select 5:00 AM - All intervals within the 5 AM hour are selected
3. The user can override the selection of a cascading select
   • For example:
     • After selecting the 5 AM hour, all intervals are selected
     • Uncheck only the 5:30 AM Interval
4. At least one interval must be selected for the Save option, under Actions to be enabled
5. Back button
   • Used to navigate back to the Create Event page
   • If the user has made selections/changes on the page and navigates back those changes will be lost, as with Manual Adjustments
6. Select Sales Item(s) button
   • Confirm that the Select Sales Item(s) button is enabled once an interval has been selected
