Hi Tess,
Thank you! It does work. And actually I don't see this behaviour of showing all items if no month has been selected. For reference, I leave here my final Data source code for the list view
{{ invoices_getData.data.filter(e => e.company_id === currentRow.id).filter(item => {
const monthNames = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];
const invoiceDate = new Date(item.invoice_date);
const invoiceMonthName = monthNames[invoiceDate.getMonth()];
const isSelectedMonth = invoiceMonthName === variable1.value.columnId;
return isSelectedMonth;
}) }}
Much appreciate your help!
