About an initial value of the select list

As the first stage display when you display the select list on the screen by using the inputfield tag,
can this initial display be changed to "** Please select it" etc. though it is displayed, "-- none --"?
Please continue your favors toward the professor when there is a person who knows.
I am sorry in poor English.

There are 2 ways:

 

1) You can set that as the "default value" in the "Picklist Values" for your field, and perform validation to check against that in your trigger.

 

2) use a Controller to list the available values, and display it through an apex:selectList component.

you can create output field below the field and make it enable when none selected.
