Thymeleaf - Suggested approach when tabular data table returns zero records (empty list)? - thymeleaf

Question

Given:
<table id="identification-data" class="pure-table">
<thead>
<tr>
<th>Name</th>
<th>DOB</th>
<th>Gender</th>
<tr>
</thead>
<tbody>
<tr th:each="row : ${identificationData}">
<td th:text="${row['Name']}">Brian Smith</td>
<td th:text="${#calendars.format(row['Date of Birth'], 'MM/dd/yyyy')}">10/11/1971</td>
<td th:text="${row['Gender']}">Male</td>
</tr>
</tbody>
</table>
If the collection ${identificationData} is empty - is there a thymeleafy way to show a message like "no data found"?
I could do something on the controller side like:
if (identificationData.isEmpty()){
model.addAttribute("identificationDataNotFound", Boolean.TRUE);
}
model.addAttribute("identificationData", identificationData);

Answer 1

The most "thymeleafy" way that I can think of is to conditionally render a <tbody> containing the "No data found" message if the list is empty. You can use the utility object #lists to check if the list is empty in the UI (saving you one more boolean model attribute)
<tbody th:if="${not #lists.isEmpty(identificationData)}">
<tr th:each="row : ${identificationData}">
...
</tr>
</tbody>
<tbody th:if="${#lists.isEmpty(identificationData)}">
<tr>
<td colspan="3">No Data found</td>
</tr>
</tbody>
