When adding mybookings widget to website built on Wix platform, the calendar date picket is cut off. Please check how to fix this issue.
Why does it happen?
Wix platform allows to add widgets only into iframe of the fixed size, that's why any content which is bigger the size of iframe will be cut off.

You can adjust the numbers for width and height and see if the code will fit into the new iframe size. Please, see this this link which will show you how to make the adjustments.
