Menu
I have this code
<div th:class="form-group">
<td><label class="control-label leftMargin10 rightMargin10" scope="col" th:text="#{insertHours.hhFrom}">Attivita'</label></td>
<td><select class="form-control" th:field="*{hhFrom}">
<option th:each="i : ${#numbers.sequence(0, 23)}" th:value="${i}" th:text="${i}" th:selected="${ i==9 } ">Options</option>
</select>
</td>
</div>
When I try to add a condition in th:selected it doesn't work.
I have also replaced with this code:
th:attr="${i==9}? selected=selected: '' "
but the result is the same.
The HTML
<select class="form-control" id="hhFrom" name="hhFrom">
<option value="0" selected="selected">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
<option value="13">13</option>
<option value="14">14</option>
<option value="15">15</option>
<option value="16">16</option>
<option value="17">17</option>
<option value="18">18</option>
<option value="19">19</option>
<option value="20">20</option>
<option value="21">21</option>
<option value="22">22</option>
<option value="23">23</option>
</select>
Thanks in advance to answers

Request parameters can be easily accessed in Thymeleaf views. Request parameters are passed from the client to server like: https://example.com/query?q=Thymeleaf+Is+Great! In the above example if parameter q is not present, empty string will be displayed in the above paragraph otherwise the value of q will be shown.
You can also change the value in the controller, just make a Java object from $client.name and call setClientName. public class FormControllModel { ... private String clientName = "default"; public String getClientName () { return clientName; } public void setClientName (String value) { clientName = value; } ... }
You can use the "th:text=#{variable}" to print a variable in the Thymeleaf.
We use th:action to provide the form action URL and th:object to specify an object to which the submitted form data will be bound. Individual fields are mapped using the th:field=”*{name}” attribute, where the name is the matching property of the object.
You cannot use th:field along with th:selected.
If you replace th:field with name=someMeaningfullName the code will work just fine.
