Here you go:

<select size="5">
    <option value="1">Item #1</option>
    <option value="2">Item #2</option>
    <option value="3">Item #3</option>
    <option value="4">Item #4</option>
    <option value="5">Item #5</option>
    <option value="6">Item #6</option>
    <option value="7">Item #7</option>
</select>
