Truly conditional domain fields?

[namhost]

I found this which allows me to add a fields during domain configuration. I used this to add a dropdown where the user can select:
 - Company
 - Individual

I also have two other fields:
 - Company Name
 - Your Name

Using conditional "Conditional Requirements", i was able to get add the code below to public_html/resources/domains/additionalfields.php:

foreach ($domainExtensions as $domainExtension)
{
  $additionaldomainfields[$domainExtension][$legalTypeLabel] = array(
    "Name" => $legalTypeLabel,
    "Type" => "dropdown",
    "Options" => '1|Company,2|Individual',
    "Required" => true,
  );

  $additionaldomainfields[$domainExtension]["Company Name"] = array(
    "Name" => "Company Name",
    "Type" => "text",
    "Size" => "100",
    'Required' => [
      $legalTypeLabel => [1],
    ],
  );

  $additionaldomainfields[$domainExtension]["Your Name"] = array(
    "Name" => "Your Name",
    "Type" => "text",
    "Size" => "100",
    'Required' => [
      $legalTypeLabel => [2],
    ],
  );

}

This works great and gives me this (see attachment).

So the problems I have:

• It's showing a * next to both fields - I expect it to only show the asterisk next to the field that is required. So therefore, at first it must show the one field as required, then the second
• But ideally, I want the whole field hidden when it's not required.

So my questions:

1. Is there a way to add custom javascript upon field generation that can handle the show and hide logic as needed?
2. Or will I just have to add my own custom javascript somewhere else? And if so, where?

Thanks!
