DevExtreme Vue - Appointment Collector

Appointments are aggregated in an appointment collector when the limit of full-sized appointments per cell is exceeded. Users should click on it to open a drop-down list of appointments.

Scheduler Appointment Collector and Drop-Down List

Use the appointmentCollectorTemplate and dropDownAppointmentTemplate options to customize the elements.

In the following code, the compact and non-compact appointment collectors have different texts, and a custom button that opens a details form is added near each appointment:

jQuery
JavaScript
CSS
$(function () {
    $("#schedulerContainer").dxScheduler({
        // ...
        dropDownAppointmentTemplate: function (data, index, element) {
            var container = $("<div>" + data.text + "</div>");
            var button = $("<span class='edit'>").dxButton({ icon: "event" });
            element.append(container.append(button));
        },
        appointmentCollectorTemplate: function(data, element) {
            if(data.isCompact) {
                element[0].innerText = data.appointmentCount;
            } else {
                element[0].innerText = "Total: " + data.appointmentCount;
            }
            element.addClass("collector");
        }
    });
});
.edit{
    margin-left: 10px;
}
.collector {
    font-style: italic;
    color: aliceblue;
}

In case of jQuery, you can also use a 3rd-party template engine to customize the widget's appearance. See the 3rd-Party Template Engines article for more information.
