Hi Gerson,
Greetings from Syncfusion Support.
We have prepared a sample to hide the ‘plus’ and ‘calendar’ icon in the header which can be viewed from the following link.
span.e-btn-icon.e-icon-add.e-icons.e-icon-left,
span.e-btn-icon.e-icon-today.e-icons.e-icon-left {
display: none;
}
Regards,
Nevitha
