Hello, 

Only combo value is submitted. 

If you want to send values of the checked options, you can use the following approach:

set onsubmit event handler that will place to some hidden input checked value. 

The example:

<form onsubmit="get_checked()" ...><input type="hidden" id="check">...</form>

...

function get_checked(){

document.getElementById("check").value = combo.getChecked();

}

Hello, 

If you want to preselect some options, you can do in in the xml:

<option value = "..." checked="1">...</option>

Moreover combo API can be used:

combo.setChecked(option_index,1);
