</ListView>

Vanilla JS:

var collectionView = require("de.marcelpociot.collectionview");

var win = Ti.UI.createWindow({backgroundColor: 'white'});

// Create a custom template that displays an image on the left, 
// then a title next to it with a subtitle below it.
var myTemplate = {
	childTemplates: [
    	{                            // Title 
        	type: 'Ti.UI.Label',     // Use a label for the title 
	        bindId: 'info',          // Maps to a custom info property of the item data
            properties: {            // Sets the label properties
    	        color: 'black',
        	    font: { fontFamily:'Arial', fontSize: '20dp', fontWeight:'bold' },
            	left: '60dp', top: 0,
        	}
        },
	    {                            // Subtitle
    	    type: 'Ti.UI.Label',     // Use a label for the subtitle
        	bindId: 'es_info',       // Maps to a custom es_info property of the item data
            properties: {            // Sets the label properties
	            color: 'gray',
    	        font: { fontFamily:'Arial', fontSize: '14dp' },
        	    left: '60dp', top: '25dp',
            }
	    }
    ]
};

var listView = require("CollectionView")".createCollectionView({
	backgroundColor: "white",
	top: 0,
	left: 0,
	width: Ti.UI.FILL,
	height: Ti.UI.FILL,
    // Maps myTemplate dictionary to 'template' string
    templates: { 'template': myTemplate },
    // Use 'template', that is, the myTemplate dict created earlier
    // for all items as long as the template property is not defined for an item.
    defaultItemTemplate: 'template',
    
    // Context menu options
    showContextMenu : true,
	contextMenuStrokeColor : "red",
	contextMenuItems : [
		{
			tintColor: "red",
			selected: "/images/UploadIconSelected.png",
			unselected:"/images/UploadIcon.png",
		},
		{
			tintColor: "red",
			selected: "/images/TrashIconSelected.png",
			unselected:"/images/TrashIcon.png",
		}
	],
    
    // ANDROID ONLY
    columnWidth: 150,
    verticalSpacing: 10,
    horizontalSpacing: 10
});
var sections = [];

var fruitSection = collectionView.createCollectionSection({ headerTitle: 'Fruits / Frutas'});
var fruitDataSet = [
	// the text property of info maps to the text property of the title label
    // the text property of es_info maps to text property of the subtitle label
    // the image property of pic maps to the image property of the image view
    { info: {text: 'Apple'}, es_info: {text: 'Manzana'}, properties: {height:150,width:150}},
    { info: {text: 'Apple'}, es_info: {text: 'Manzana'}, properties: {height:150,width:150}},
];
fruitSection.setItems(fruitDataSet);
sections.push(fruitSection);

listView.setSections(sections);
win.add(listView);
win.open();
