</li>

When I click on li he has to expand her to width: 766px and send the div listagemEsc for margin-left:383px. He’s expanding to 766px only he does it at all li, and not just the one I clicked on. I couldn’t test the rest.

Two amendments:

• uses $(this).css() to apply only to the element you clicked
• uses .next() to fetch the brother div immediately afterwards, instead of calling on the selector all elements with the class listagemEsc. Or to be more specific el.closest('.membrosClick').find('.listagemEsc').css("margin-left", "383px");

Final result:

$(".membrosClick").click(function () {
    var el = $(this);
    el.css("width", "766px");
    el.children().fadeToggle();
    el.next().css("margin-left", "383px");
});
