Grouping

Combo groups

There is an opportunity to organize groups of interdependent combos. When you select option in a parent combo , a value of selected option is sent with a request and the child combos are filled up with the necessary options.

Combo groups in different containers

Method attachChildCombo allows to set child combo in another container.
It has two parameters:

object of the child combo
path to script which generates xml

 
    var z3=new dhtmlXCombo("combo_zone3","alfa3",200);
    z3.loadXML("3.php")
        
    var z2=new dhtmlXCombo("combo_zone2","alfa2",200);
    z2.enableFilteringMode(true);    
    z2.attachChildCombo(z3,"3.php");
    z2.loadXML("2.php");    
        
    var z=new dhtmlXCombo("combo_zone","alfa",200);
    z.enableFilteringMode(true);
    z.attachChildCombo(z2,"2.php");
    z.loadXML("1.xml")

Combo groups in the same container

You can define a child combo in the same container with its parent by setAutoSubCombo(url,name) method.

 
    var z4=new dhtmlXCombo("combo_zone4","alfa4",200);
    z4.enableFilteringMode(true);
    z4.loadXML("1.xml")    
    var z5 =  z4.setAutoSubCombo("2.php","alpha5")
    var z6 =  z5.setAutoSubCombo("3.php","alpha6")
