Hi @harry_c2020,
You could try the following:
$("[data-name='tab_5']").find("div.control").each(function () {
$(this).children().enable(false);
});
You could break it down to be more specific for inputs, selects and textareas (also radio buttons, etc. as needed):
$("[data-name='tab_5']").find("input, select, textarea").enable(false);
