End of Css
Start Menu
<nav class="columns" id="actions-sidebar">
<ul class="side-nav">
<!-- Início Link para Menu DadosPrincipais -->
<li><?= $this->Html->link('> '.__('Student Data'), '#DPrincipais', ['style' => $dataButton]) ?></li>
<li><a href="#TrabalhoRendimento">> Trabalho Rendimento</a></li>
<li><?= $this->Html->link('> '.'Trabalho','#TrabalhoRendimento', ['style' => $matriculaButton]); ?></li>
</ul>
</nav>
End of Menu Starting Javascript
const divs = [...document.querySelectorAll('#DPrincipais,#TrabalhoRendimento,#Referencia,#Comprovante')];
const botoes = [...document.querySelectorAll("li")];
for (let i = 0; i < botoes.length; ++i){ //percorrer todos os botoes
botoes[i].addEventListener("click", function(){ //definir o click para cada um
divs.forEach(div => div.style.display = "none"); //esconder todos os divs
divs[i].style.display = "block"; //mostrar o que foi clicado
});
}
divs.forEach(div => div.style.display = "none"); //iniciar todos escondidos
divs[0].style.display="block"; //Exibe só a primeira div
