For each operator in Thymeleaf

Question

I can not find syntax for building simple for-each-loop in Thymeleaf template. I\'m not satisfied with just th:each=\"\" attribute, because it copi

Answer 1

The th:block solution is definitely the best one, but alternatively you can also try using th:remove="tag" in order to remove the containing tag:

<table>
   <tbody th:each="user : ${users}" th:remove="tag">
      <tr>
         <td th:text="${user.login}">...</td>
         <td th:text="${user.name}">...</td>
      </tr>
      <tr>
         <td colspan="2" th:text="${user.address}">...</td>
      </tr>
   </tbody>
</table>

The benefit of this approach is that you can also pass a Thymeleaf expression to th:remove in order to only remove the tag conditionally, e.g. if you want only some users to be included in a <tbody>, besides having other interesting uses.

Here is the documentation for th:remove.

Answer 2

Use th:block as stated in the Thymeleaf guide

th:block is a mere attribute container that allows template developers to specify whichever attributes they want. Thymeleaf will execute these attributes and then simply make the block disappear without a trace.

So it could be useful, for example, when creating iterated tables that require more than one <tr> for each element:

<table>
   <th:block th:each="user : ${users}">
      <tr>
         <td th:text="${user.login}">...</td>
         <td th:text="${user.name}">...</td>
      </tr>
      <tr>
         <td colspan="2" th:text="${user.address}">...</td>
      </tr>
   </th:block>
</table>
