Populate form's data in modal with fragment thymeleaf - spring

Question

I'm using Spring boot and Thymeleaf.I have a modal form to create/edit information:
<div class="modal" id="myModal" th:fragment="content">
<form th:object="${object}">
<div class="modal-dialog">
<div class="modal-content">
<!– Modal Header –>
<div class="modal-header row">
<div class="col-md-10">
<h4 class="modal-title">Create/Edit</h4>
</div>
<div class="col-md-2">
<button type="button" class="close" data-dismiss="modal"
style="float: right;">×</button>
</div>
</div>
<!– Modal body –>
<div class="modal-body">
<div class="form-group">
<label for="ID">ID</label>
<input type="text" class="form-control" id="ID" placeholder="ID"
th:field="*{id}">
</div>
<div class="form-group">
<label for="name">Name</label>
<input type="text" class="form-control" id="name" placeholder="name"
th:field="*{name}">
</div>
<div class="form-group">
<label for="description">Description</label>
<input type="text" class="form-control" id="description" placeholder="Description"
th:field="*{description}">
</div>
<div class="form-group">
<label for="date">Date</label>
<input type="date" class="form-control" id="date" placeholder="Date"
th:field="*{date}">
</div>
<div class="form-group">
<label for="other">Other</label>
<input type="text" class="form-control" id="other" placeholder="other"
th:field="*{other}">
</div>
</div>
<!– Modal footer –>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Submit</button>
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</form>
</div>
I can't place inside my index.html because the Object is null. When user click button to crate/edit user, the modal will pop-up with data.
The button is:
<button type="button" class="btn btn-success" onclick="triggerModal(null)">Create New</button>
My Jquery function:
function triggerModal(id) {
if(id==null){
var url = "/create";
}else{
var url = "/create/{"+id+"}";
}
$('#content').load(url);
$('#myModal').modal({show:true});
}
The controller:
#GetMapping(value = {"/create","/create/{id}"})
public String createObject(Model theModel, #PathVariable(required = false)String id){
if(id!=null){
Optional<Object> object= objectRepository.findById(id);
if(object.isPresent()){
theModel.addAttribute("Object", object.get());
return "/form-modal::content";
}
}
theModel.addAttribute("Object", new Object());
return "/form-modal::content";
}
This is the div tag I place on the index.html
<div id="content"></div>
I have successfully insert modal to HTML body with data loaded but the modal is not displayed correctly.

I have solved it.
Just place the th:fragment inside the modal class:
<div >
<form th:object="${object}" th:fragment="content">
<div class="modal-dialog">
<div class="modal-content">
<!– Modal Header –>
<div class="modal-header row">
<div class="col-md-10">
<h4 class="modal-title">Create/Edit</h4>
</div>
<div class="col-md-2">
<button type="button" class="close" data-dismiss="modal"
style="float: right;">×</button>
</div>
</div>
<!– Modal body –>
<div class="modal-body">
<div class="form-group">
<label for="ID">ID</label>
<input type="text" class="form-control" id="ID" placeholder="ID"
th:field="*{id}">
</div>
<div class="form-group">
<label for="name">Name</label>
<input type="text" class="form-control" id="name" placeholder="name"
th:field="*{name}">
</div>
<div class="form-group">
<label for="description">Description</label>
<input type="text" class="form-control" id="description" placeholder="Description"
th:field="*{description}">
</div>
<div class="form-group">
<label for="date">Date</label>
<input type="date" class="form-control" id="date" placeholder="Date"
th:field="*{date}">
</div>
<div class="form-group">
<label for="other">Other</label>
<input type="text" class="form-control" id="other" placeholder="other"
th:field="*{other}">
</div>
</div>
<!– Modal footer –>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Submit</button>
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</form>
</div>
And change the div tag in the index file:
<div class="modal" id="myModal"></div>
