// This script supports an unlimited number of linked combo boxed

// Their id must be "combo_0", "combo_1", "combo_2" etc.

// Here you have to put the data that will fill the combo boxes

// ie. data_2_1 will be the first option in the second combo box

// when the first combo box has the second option selected

 

 

// first combo box

 

data_1 = new Option("1", "$");

Scripting... lo muevo a Webmaster...

Yo por hay tengo uno de 4 que funciona con BD, php y Javascript.

 

Se le puede agregar un 5. pero da problemas si le agregas un 6 (segun otros usuarios)

 

el original tenia 3 y yo le agrege el 4.

 

Era de Pais, Region, Cuidad, y yo le agregue calle n_n

 

Si tienes para soportar BD te lo busco y te digo como funciona
