Сделать древовиднй вывод из div

Нужно, чтобы при клике на блок class="trg_no_active открывались скрытые блоки, которые находятся под тем блоком, на который кликнули. Но нужно открыть не все, а только, которые имеют отступ текущий + 25. Т.е. если кликнем на блок, который имеет отступ 25, то открыть 25+25=50 отступ:

var n=Number(margin); // 25 
var k=n+25;

var i=$(this).attr("id"); // 6 
$("div[data="+k+"]").each(function(){

});

Проблема в том, что мне нужно показать скрытые div'ы, которые идут после текущего, и не показывать те, которые идут выше дерева. div'ы идут друг за другом. Вложения определяются отступом margin. Нужно остановить цикл, когда будет вхождение margin, равное текущему.
