Is there only one element type option for an array?

[Panna]

I'm creating an array which contains both string and double, just wondering if I can have multiple element type options for one array column? Thanks

Elements of any type that share a least common type can be used, https://docs.databricks.com/sql/language-manual/functions/array.html#arguments.

Please correct me if I misunderstood to understand the requirement.
