Is it another alternative to use DHTMLX to change combo mult


If you mean dhtmlxcombo - fastest way to load data - load it from XML
Also addOption command can process an array of options by single call

Instead of
    combo.addOption(a,b);
    combo.addOption(a,b);
    combo.addOption(a,b);
It possible to use
    combo.addOption([a,b],[a,b],[a,b]);

Combo supports dynamic loading mode ( suggest mode ) which allow to load data on demand - this may be the best approach for huge option lists.
