Ability to clear the value from a dropdown field

[muralivenneti]

Users should have the ability to clear the value selected from a dropdown field especially from non-mandatory dropdowns if user selects a value accidentally, currently it forces user to select a value from dropdown instead leaving it as blank. Usually, dropdowns add a blank value to the list of values which gives the user the ability to set the dropdown to blank.
