<fieldset>
A group of fields under one shared question.
Indispensable for radio buttons and checkboxes: without <fieldset> and <legend>, someone on a screen reader hears the options without ever hearing the question they answer.
The disabled attribute switches off every control inside at once — except any in the first <legend>.
<fieldset>
<legend>Sort the drawer by</legend>
<label><input type="radio" name="ordem" value="alfabetica"> name</label>
<label><input type="radio" name="ordem" value="coleta"> collection number</label>
