Question: I thought that adding a `"value"` attribute set on the `<select>` element below would cause the `<option>` containing my provided `"value"` to be selected by default:

```html
<select name="hall" id="hall" value="3">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>
```

However, this did not work as I had expected. How can I set which `<option>` element is selected by default?

Answer: 
I was having some troubles with it because I need some way to choose the option dynamically accordingly to the value that I have in the database. The script bellow works like a charm to me:

```
<?php
//pick the value of database
$selected_sexo = $query['s_sexo'];
?>

<select name="s_sexo" id="s_sexo" required>
  <option <?php if($selected_sexo == 'M'){echo("selected");}?> value="M">M</option>
  <option <?php if($selected_sexo == 'F'){echo("selected");}?> value="F">F</option>
</select>

```
