Statement of the proplem: Right to left support is very important for this date picker it is fantastic component and consider the most powerfull date picker component for vue.js but the only thing missing for arabic comunity is right to left support

Solution: when select loacale to ar the component layout should be transfered to rtl direction

Alternative solution: add rtl boolean prop to set rtl direction

notes: when set dir to rtl the layout not transfered to rtl the only thing th action arrow changed to incorrect direction
