droppable in Yii

hello everyone, im new in this and i want to know if is possible when i use the droppable won’t reset when i refresh, i mean my droppable works fine, but when i refresh all reset, i think that i need to set in my box something in php when i drop some minibox to stay there, any idea how i can start?

I don’t know anything about the “droppable” extension but it seems you need an ajax function that store settings and boxes positions into the database.
