[Php-calendar-discussion] change subject feild to drop down select

[p.dieperink <p.d...@ch...>]

In the add events form of the calendar I would like to change the subject
entry field from a standard text field to a drop-down select field.
This because I only have four standard subjects my users can choose from
 
Can anybody help where I can change this
