This is my select, I have tried to use it for a long time, I do not know how it works, I see that many great websites use it and the user selects the city, it shows the respective content, but the URL does not change.
<form action="cid.php" method="get">
<select name="cidade" id="cidade">
<option>Selecione</option>
<option value="Cidade 1">Cidade 1</option>
<option value="Cidade 2">Cidade 2</option>
<option value="Cidade 3">Cidade 3</option>
</select>
<input type="submit" name="submit" id="submit" class="botao" value="Ok">
</form>
Who can help or give me a direction, thank you very much.
