I have the following select, every time I select an option it reloads the page, so that's fine, but I want to make clicking on the option nUpgrade, it just does not update the page, does it have? Thanks!
<select id="filtro" name="filtro" class="form-control" onchange="this.form.submit()">
<option value="">Selecione</option>
<option value="assunto"></option>
<option value="nAtualiza"></option>
</select>
