Set default value of single value parameter to select all

I am using a string parameter in a calculated field, hence I need to set its default value. How can I set it to “Select All” by default?

Hello @adevaraj , welcome to the Quicksight community!

As long as you did not set a default value, the parameter should be set to show all values passed from the parameter. Depending on your use case you may need to attach it to a control for it to be dynamic for your end user.

I was able to resolve it by setting the default value to null and customized value to nu ll too.
