Idea Summary
New popup LOV needs to been able to remove selected value to allow null

Use Case
Using popup LOV as item type and setup to allow null values, once you change from null to a value, you cannot go back to null.

There is no way to delete assigned value on the item.

Changing to “manual entry” also removes the display value and only shows the return value.

Preferred Solution (Optional)
having an ‘X’ icon besides the LOV icon on popup LOV would be useful
