Dynamically ADD select options to a SUBLIST SELECT field created via SuiteScript UI Builder APIs

The goal of NetSuite user is to dynamically 'ADD' select options to a sublist 'SELECT' field created via SuiteScript UI Builder APIs. Is wanted to source the values of the select field from a search. For this example, is needed to get all inventory items from a specific subsidiary and then make those items selectable on sublist select field under Suitelet form.

 
This solution needs a combination of a Client Side script and a Suitelet script. Below is a sample code that searches all Inventory Items from a specific subsidiary and then populate the select fields with the results of the search.
 
Sample Suitelet Script Code:
 
function main(request, response) {
 
 var form = nlapiCreateForm('Items', false);
 var sublist = form.addSubList('custpage_items', 'inlineeditor', 'Items');
 var itemField = sublist.addField('custpage_item', 'select', 'Item');
 form.setScript('customscript_populate'); //attach the client script code
 response.writePage(form);
}
 
Client Side Script Code:
 
function pageInit() {
 nlapiRemoveLineItemOption('custpage_items', 'custpage_item'); //remove all existing select options
    nlapiInsertLineItemOption('custpage_items', 'custpage_item', '', '', true); //Insert null value and default it to selected
 
 var filters = new Array();
 filters[0] = new nlobjSearchFilter('type',null,'is','InvtPart'); //Item type will be Inventory Item
 filters[1] = new nlobjSearchFilter('subsidiary',null,'is','1'); //Subsidiary is the first one
 
    var results = nlapiSearchRecord('item', null, filters, new nlobjSearchColumn('displayname')); // search all inventory items which are for a specific subsidiary
    for (var i in results)
    {
        var id = results[i].getId();
        var name = results[i].getValue('displayname');
        nlapiInsertLineItemOption('custpage_items', 'custpage_item', id, name); //populate the sublist select field with options
    }
}
 
The client script is deployed on the Page Init function of the Suitelet so that it populate the sublist select field upon load of the Suitelet form.
