Please help: custom time picker in form

[stwong]

Hello,

We've 2 questions about time picker in an app with a simple form:
1. We want to hide all except Date & Time from time picker. We specify following in appserver/static/dashboard.css

 div[id^='presets_view'],
 div[id^='daterange_view'],
 div[id^='advanced_view'],
 div[id^='relative_view'],
 div[id^='realtime_view'] {
     display: none;
}

However, the Presets tab is always displayed. Can we hide it?

1. Possible to hide some options in the Presest tab, say only shows the "Relative" ones ?

We're running Splunk 7.0.

Thanks a lot.
Best Regards,
