Thymeleaf th tag in blc tag

my problem is following: in this code

    <header>
        <h1 th:utext="${BLC_PAGE.pageFields[menu_name]}"></h1>
    </header>

    <blc:menu resultVar="menuItems" menuName="${BLC_PAGE.pageFields[menu_name]}" />
    <ul th:if="${not #lists.isEmpty(menuItems)}">
        <li th:each="menuItem : ${menuItems}">

            <a th:href="@{${menuItem.url}}" th:class="${menuItemStat.first}? 'home'">
                <span th:utext="${menuItem.label}"></span>
            </a>

        </li>
    </ul>

the line <h1 th:utext="${BLC_PAGE.pageFields[menu_name]}"></h1> gets the name of actual menu. I need the menuName in this line <blc:menu resultVar="menuItems" menuName="${BLC_PAGE.pageFields[menu_name]}" /> to do the same thing, but "${BLC_PAGE.pageFields[menu_name]}" is not appropriate, as it is from thymeleaf tags library. Any idea how to get this this value in blc:menu tag?

Solution

  • In order to resolve the Thymeleaf expression ${BLC_PAGE.pageFields[menu_name]}, you will need to wrap it like so: th:attr="menuName=${BLC_PAGE.pageFields[menu_name]}". Because menuName is not a standard HTML attribute, you won't be able to simply add the Thymeleaf namespace to menuName (i.e., th:menuName), and, without the th: namespace, Thymeleaf doesn't know that it needs to resolve any expressions. The Thymeleaf attr attribute allows you to use non-standard HTML attributes with Thymeleaf. For more information on setting attribute values using Thymeleaf you can review their documentation.
