Calendar overflows viewport when too wide

[zipper]

Describe the bug
When input with calendar is close to the right edge of the window, calendar might overflow viewport and cause horizontal scrollbar to appear.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://easepick.com/configurator/
2. Set options calendar to 2 and grid to 2.
3. Resize the window to ~1100px.
4. When the calendar is opened, it overflows the window to right, causing scrollbar to show

Expected behavior
The calendar is aligned to the left edge of the associated input. I would expect it to move right, when there is not enough space.
