Struggling with generating forms using AJAX, Javascript, and HTML depending on the selection made from a drop-down menu

I am in need of a simple web form for work submissions within my organization. These submissions will fit into 4 Categories, each requiring unique information. Currently, I have a basic form set up with fields such as Requested Name, Requested Date, Acquisition, and Type of Request which is a drop-down with 4 options.

What I am aiming for is that based on the selection made in the drop-down, the user should see a corresponding form displayed below with a table containing more input fields and text boxes.

However, I am encountering multiple issues, such as only seeing one table row instead of all selected options. It seems like I might not be tackling the problem in the right way. So, I am reaching out for assistance or guidance to steer me in the correct direction.

$(document).ready(function() {
   $('select[name="select_main_table"]').change(function() {
      $("#main_table tr").hide().eq(this.value-1).show();
   }).change();
});



      <td><label for="typeofrequest">Type of Request</label></td>
      <td><select name="select_main_table">
        <option value="" selected="selected"> - Choose -</option>
        <option value="1">Office Move</option>
        <option value="2">Office Closure</option>
        <option value="3">New Office</option>
        <option value="4">New Service</option>
      </select>          </td>
      <td>&nbsp;</td>
    </tr>

   <table id="main_table">
    <tr> 
      <td><label for="sitecontactname">Site Contact Name</label></td>
      <td><input type="text" class="validate[required,custom[sitecontactname]]" name="sitecontactname" id="sitecontactname" value="" /></td>
      <td>&nbsp;</td>
    </tr>

    <tr>  
      <td><label for="sitecontacttitle">Site Contact Title</label></td>
      <td><input type="text" class="validate[required,custom[sitecontacttitle]]" name="sitecontacttitle" id="sitecontacttitle" value="" /></td>
      <td>&nbsp;</td>
    </tr>

    <tr> 
      <td><label for="sitecontactemail">Site Contact Email</label></td>
      <td><input type="text" class="validate[required,custom[sitecontactemail]]" name="sitecontactemail" id="sitecontactemail" value="" /></td>
      <td>&nbsp;</td>
    </tr>

    <tr>  
      <td><label for="sitecontacttelephonenumber">Site Contact Telephone Number</label></td>
      <td><input type="text" class="validate[required,custom[sitecontacttelephonenumber]]" name="sitecontacttelephonenumber" id="sitecontacttelephonenumber" value="" /></td>
      <td>&nbsp;</td>
    </tr>
   </table>
