How to add value in java list in thymeleaf

I am working with Java ArrayList and thymeleaf. I need to use the list in thymeleaf for adding value dynamically. I don't understand how to do that?
Model
public class MedicineDTO {
private Long brandId;
private Long stockId;
private double quantity;
private double discount;
private double total;
}
public class InvoiceDTO {
private String customerName;
private String mobileNumber;
private List<MedicineDTO> medicineDTOList;
private double averageDiscount;
private double totalDiscount;
private double grandTotal;
}
Controller
#RequestMapping(value = "/pos")
public String getPOS(Model model) {
List<Brand> brandList = brandService.getAllBrands();
List<MedicineDTO> medicineDTOList = new ArrayList<>();
InvoiceDTO invoiceDTO = new InvoiceDTO();
invoiceDTO.setMedicineDTOList(medicineDTOList);
model.addAttribute("medicinedto", new MedicineDTO());
model.addAttribute("invoicedto", invoiceDTO);
model.addAttribute("brands", brandList);
return "pos";
}
#PostMapping(value="/pos/payment")
public String makePayment(InvoiceDTO invoiceDTO){
System.out.println(invoiceDTO);
service.makePayment(invoiceDTO);
return "invoice/invoice";
}

I am trying to add list value in thymeleaf frontend this way. I am passing two object from controller to html. And i am using <div th:text="${invoicedto.medicineDTOList.add(medicinedto)}" th:remove="all"></div> for adding medicindto object. But It passes null list to controller. Do you have any idea how i solve my problem? thanks in advance.

Thymeleaf is used to process HTML templates, add data to it, do some checks such as th:if, th:unless and also loops through an array of objects using th:each etc. But all of this is done on the server side. Once the HTML template has been delivered to the client (the browser in this case), thymeleaf is not applicable there.
So on the client side, you have to rely on HTML and JavaScript to get everything done, including preparing your data to be submitted in the form.
Based on the explanation above, you can do some more research on how to handle list on html forms. I found this solution to be appropriate for your use case, you can study it and use it.
He has used Ratings[' + rating + '][Value] in his solution, you will use something like medicineDTOList[' + index + '][brandId]. Why medicineDTOList? because in InvoiceDto which is your form's th:object, the list of MedicineDto is called medicineDTOList.
The [index] refers to the array index, which will correspond to the position of the MedicineDto in your arraylist and [brandId] correspond to the property of the MedicineDto at that index.
Upon submitting the form, java will parse the form's data into your "DTO" which is InvoiceDTO.

Receiving 400 bad request when sending a POST with Angularjs (datepicker component)

My web app is basically: jsp + angularjs, but this datepicker is running with jQuery because of the template I am using.
Before explaining what is happening, my DTO's attributes matches my entity attributes, both java.util.Date, I am just informing that I already verified the attributes type because I got many 400 bad requests because of that.
I have a modal where I have many fields, but I inserted recently two datepickers (bootstrap) and till then app is crashing, when I send the POST via ajax to my java controller, I am receiving a bad request (400), I think that it is because the format is wrong (mm/dd/yyyy). I formatted correctly the date to pt_BR for Brazil but it is not working.
BoxApp.controller("UsuariosController", function($scope, $http) {
$scope.usuarios={};
$scope.usuariosParaAlterar={};
$scope.iniciar = function() {
$http.get('/boxmlV2/usuario').success(function (response) {
$scope.usuarios = response;
});
};
$scope.iniciar();
$scope.setSelected = function(selecao){
$scope.usuariosParaAlterar = selecao;
};

$scope.submitted = false;
$scope.submitForm = function(formUsuarios) {
$scope.submitted = true;
if (formUsuarios.$valid) {
$("#dataValidadeConta").datepicker({
format: 'dd/mm/yyyy',
language: 'pt-BR'
});
$("#dataValidadeSenha").datepicker({
format: 'dd/mm/yyyy',

});
$scope.editaUsuario();
}
};
$scope.editaUsuario = function() {

The date formatting to pt_BR only applies to how it is displayed in the datepicker control. Note that you are sending back a string mm/dd/yyyy to the server, you need to be sure that it is parsed as such at the controller.

Converting HTML form to PDF using iText

I tried to do an HTML form with "generate pdf" button. The button converts HTML form to PDF successfully, but it doesn't retrieve the text field values (firstname) in HTML to PDF.
