Value default with thymleaf in a combobox - html

Question

I have a problem with thymleaf. I have a form with a combobox and some fields. I want put default value in the combobox and the clausure "selected" not working for me.
The code is this:
<select class="dsp-inline form-control" th:field="*{tipoDocumento}" required="required" th:disabled="${permisoXestion == false}">
<option value="" th:text="#{select.option.default}"> </option>
<option th:each="row : ${tipoDocumento}" th:value="${row}" th:text="#{${row.value}}" th:selected="#{${row==2}}"></option>
</select>
Where "tipoDocumento" is a enum with two values:
public enum TipoDocumento {
PUBLICO("documento.tipo.publico"),
PRIVADO("documento.tipo.privado");
private String property;
private String value;
private TipoDocumento(String property) {
this(property, null);
}
private TipoDocumento(String value, String property) {
this.value = value;
this.property = property;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public String getProperty() {
return property;
}
public void setProperty(String property) {
this.property = property;
}
}
Can someone help me?

The selected tag should work. Remember it need to be added like selected="selected". I have used it on several selects and it always work. Also, in your th:each you need to remove the th:selected="#{${row==2}}" element, otherwise your first option won't be the default one.
<select class="dsp-inline form-control" required="required" th:disabled="${permisoXestion == false}">
<option value="" th:text="#{select.option.default}"></option>
<option th:each="row, iter : ${tipoDocumento}" th:value="${row}" th:text="#{${row.value}}" th:selected="${iter.count eq 2} ? 'selected' : 'false'"></option>
</select>

if you use the th:selected you cannot not use the th:field. You have to replace it with a name attribute.
So, can you replace
<select class="dsp-inline form-control" th:field="*{tipoDocumento}" required="required" th:disabled="${permisoXestion == false}">
with
<select class="dsp-inline form-control" name="tipoDocumento" required="required" th:disabled="${permisoXestion == false}">
Also, the condition of the th:selected
can you replace
th:selected="#{${row==2}}"
with
th:selected="${row==2}"
