[Javascript] Dynamically change SELECT size

[Reuben D Budiardja]

Hello,
I'm building an application where I need, if possible, to change the SELECT 
size dinamically, and change the OPTION value and text also. Is it possible 
to be done?

Basically I have 2 array, with different size, and any one of them is going 
to be element option of the SELECT, depending on what the user do (ie. 
checking a checkbox).

If this is possible, please let me know how to change the size of the SELECT 
box. 

Thanks in advance.
