Examples:

1.

// In this example, the value of the "colorClass" option and the value of the "header" property are added to the layout. 
// If the "header" property doesn't have a value, the string "Title" is inserted.
var LayoutClass = ymaps.templateLayoutFactory.createClass(
    '<h1 class="{{ options.colorClass }}">' +
    '{{ properties.header|default:"Title" }}' +
    '</h1>'
);

2.

// One of the layouts is enabled, depending on the value of the "width" option.
var LayoutClass = ymaps.templateLayoutFactory.createClass(
    '{% if options.width > 200 %}' +
    // The appropriate layout will be found in the options.
    '{% include options.wideLayout %}' +
    '{% else %}' +
    // Writing the key explicitly.
    '{% include "cluster#balloonCarousel" %}' +
    '{% endif %}'
);

3.

// Outputting an array of names to the balloon layout.
var CustomLayoutClass = ymaps.templateLayoutFactory.createClass(
    '<ul>' +
    '{% for name in properties.names %}' +
    // The "name" variable is only visible in the for ... endfor block
    '<li>{{ name }}</li>' +
    '{% endfor %}' +
    '</ul>'
);

var placemark = new ymaps.Placemark([54.83, 37.11], { 
    names: ['Logan', 'Sofia', 'Mason', 'Layla']
}, {
    balloonContentLayout: CustomLayoutClass
});

4.

// Getting the names of fields.
var CustomLayoutClass = ymaps.templateLayoutFactory.createClass(
    '<ul>' +
    '{% for key, value in properties.hash %}' +
    '<li>{{ key }} {{ value }}</li>' +
    '{% endfor %}' +
    '</ul>'
);

var placemark = new ymaps.Placemark([54.83, 37.11], { 
    hash: { key1: "value1", key2: "value2", key3: "value3" }
}, {
