If there is no space below for the select2 component to open, it opens upwards. However, there is an issue: if it opens upwards, on its initial opening, it appears with a misalignment to the left. The issue gets resolved when opened, closed, and then reopened.
there is any solution?
I created an issue. If anyone encounters the same problem, they can follow it here.
