<!-- Define a hashmap -->
<ol class="app-task-list">
  <th:block th:with="tasks=${ {{enabled: false, url: '', taskState: 'COMPLETED', titleCode: 'taskList.pre.section.checkEligibility'}} }">

  <th:block th:replace="~{ fragments/task-list :: task-list-group(${tasks}, #{taskList.pre.section.title}, 1)}" />
  </th:block>

  <th:block th:replace="~{ fragments/task-list :: task-list-group(${tasks}, #{taskList.application.section.title}, 2)}" />

  <th:block th:replace="~{ fragments/task-list :: task-list-group(${tasks}, #{taskList.apply.section.title}, 3)}" />
</ol>

<!-- Conditional CSS class append using Hashmap lookup -->
<th:block th:fragment="task-list-status-tag(taskState, id)">
  <th:block th:with="tagCSSSuffixes=${ {NOT_STARTED:'not-started', IN_PROGRESS:'in-progress', COMPLETED:'completed'} }">
    <strong class="app-task-list__task-tag" th:classappend="'app-task-list__task-tag--' + ${tagCSSSuffixes.get(#strings.toString(taskState))}" th:text="#{'taskList.task.state.' + ${#strings.toString(taskState)}}" th:id="${id}"></strong>
    </th:block>
</th:block>
