body: <p>How can I use null check inside a list in Thymeleaf.
  I have the following</p>
  
  <pre><code>&lt;tr th:each="idBean : ${idBeanLst}"&gt;
  
                  &lt;td th:text="${idBean.identifierId}"&gt;&lt;/td&gt;
                  &lt;td th:text="${idBean.idNumber}"&gt;&lt;/td&gt;
                  &lt;td th:text="${idBean.issueLocation}"&gt;&lt;/td&gt;
                  &lt;td th:text="${idBean.issueDate}"&gt;&lt;/td&gt;
                  &lt;td th:text="${idBean.expiryDate}"&gt;&lt;/td&gt;
  </code></pre>
  
  <p>idBeanLst is the list that contains identifierBean.Now I want to show the result only if idBean.idNumber !=null.How to put this check?</p>
