We have PE, and we need to create a VF page. In that page we have created a picklist which has 5 values. When we select a value from the picklist a text box next to that picklist should automatically populate a message similar to that value selected. ie., if our picklist has red, blue, green, when we select "red" then the textbox should populate this message "this is red" likewise. How we can to this? But for PE there is no Apex class how can we achieve this.
