how to add drop down options to this field?

[bn17311]

hi,

i have added an extra field for google categorys and want drop down options if empty

so far i have

<tr>                                                                                                              
            <td class="main"><?php echo TEXT_PRODUCTS_GOOGLETYPE; ?></td>
            <td class="main"><?php echo zen_draw_separator('pixel_trans.gif', '24', '15') . '&nbsp;' . zen_draw_input_field('products_googletype', $pInfo->products_googletype == 0 ? 'Health & Beauty' : $pInfo->products_googletype, zen_set_field_length(TABLE_PRODUCTS, 'products_googletype')); ?></td>
          </tr>
          <tr>

if empty this inserts the one choise i have but i would like to add extra choices

hope this makes sense
