Change daterange picker to mobile friendly datepicker of a Drupal module

Project details: Implement the regular Drupal datepicker or a different responsive datepicker for a views page where the exposed filter of the module „availability calendars“ is used. Current state: [login to view URL] How it should look like: [login to view URL] At the moment a daterange picker is used by the module but it is not really mobile friendly. This is why it must be changed. Furthermore when clicked in the textfield of „Anreise“ (Arrival) and „Abreise“ (Departure) on mobile devices the keyboard will open. This behaviour must be disabled on Android and iOS. And finally the autocomplete of the textfields must be disabled so the browser does not display options to fill in the field based on earlier typed dates which can be easily achieved by adding autocomplete=“off“ to the field input. Important notice: I can NOT give you access to ftp and Drupal admin. I will send you the modified version of the module „availability calendars“ where you have to change the datepicker. You can install and test the behaviour before on your own Drupal installation.
