Guide to setting the first tab as the default tab using Thymeleaf, Css, and Bootstrap

I am currently working on a project where I need to dynamically create tabs based on a list retrieved from my Spring backend using Thymleaf and Bootstrap. While I have managed to successfully create the tabs and content, I am facing an issue where the first tab does not open by default. However, it works fine when clicked.

<ul class="nav nav-tabs" >
        <li class="nav-item" th:each="t, tNum: ${tx}">
            <a class="nav-link" th:classappend="${tNum.first} ? 'active'"  th:href="@{'#'+ ${t.ticker}}" data-toggle="tab"><label th:text="${t.ticker}">bar title</label></a>
        </li>
    </ul>

<div class="tab-content">
        <div class="tab-pane" th:id="${t.ticker}"th:classappend="${tNum.first} ? 'active'"  th:each="t, tNum: ${tx}">
            <h3 th:text = "${t.ticker}">bar content</h3> 
</div>
</div>

Answer №1

In this documentation, it explains how to add the active class to the tab you wish to open.

 <li class="nav-item">
    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
  </li>

 <div class="tab-content" id="myTabContent">
  <div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>

You can implement this feature either through JavaScript or directly in your HTML code.
