Mapbox personalized icons with cluster and filter checkbox

I have created a map using mapbox. I add icons from an Url and a type of "filter". But I want to add a marker cluster and in and also that the filter function with checkbox to select more than one option.

This is my example. I'll tried with the Leaflet marker cluster but... I'm totally new with code then, I don´t know in what place I should put the cluster code.

I think now, the most important form me is the checkbox for the filters. I tried to make put "true" or "false" to certain values in the properties of the icon and this at final. But aren´t checkboxes :(

myLayer.on('layeradd', function(e) {
    var marker = e.layer;
    var feature = marker.feature;

    var images = feature.properties.images
    var slideshowContent = '';

marker.setIcon(L.icon(feature.properties.icon));
    for(var i = 0; i < images.length; i++) {
        var img = images[i];
    }
    var popupContent =  '<div id="' + feature.properties.id + '" class="popup">' +
                            '<h2>' + '<p align=center>'+ feature.properties.title + '</p>'+'</h2>' +
                            '<h5>' + feature.properties.description +'</h5>'

                        '</div>';

    marker.bindPopup(popupContent,{
        closeButton: false,
        minWidth: 400
    });

});



myLayer.setGeoJSON(geoJson)
.addTo(map);

$('.menu-ui a').on('click', function() {
      var filter = $(this).data('filter');
    $(this).addClass('active').siblings().removeClass('active');
    myLayer.setFilter(function(f) {

        return (filter === 'Development') ? true : f.properties[filter] === true;
    });
    return false;
});

Thanks and have a nice day! :)
