title: Partial Update of a webpage ASP.NET Core radiobuttons
body: <p>Web Page Image of the Interface
  <a href="https://i.stack.imgur.com/P7GnC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/P7GnC.png" alt="enter image description here" /></a>
  The image above shows what the interface should look like. The red highlight needs to be dynamic.
  Depending on the API selection (which is dynamic depending on a config file).</p>
  <p>This is the example config I am using.</p>
  <pre><code>&quot;APIS&quot;: [
  {
    &quot;APIID&quot;: 0,
    &quot;APIName&quot;: &quot;First&quot;,
    &quot;Enabled&quot;: true,
    &quot;APIPort&quot;: 1234,
    &quot;Endpoints&quot;: [
      {
        &quot;ID&quot;: 1,
        &quot;Enabled&quot;: true,
        &quot;FriendlyName&quot;: &quot;First Second Option&quot;,
        &quot;Mapping&quot;: &quot;[MAPPING HIDDEN]&quot;
      }
    ]
   }
  ]
  </code></pre>
  <p>When I select the other API radio button, it needs to update the Endpoint options (as shown on the image).
  The endpoint options can vary in length (One API may have one, another may have 2).</p>
  <p>I have been looking for a solution for a few days, and have been unable to find one.</p>
  <p>I believe I need to use AJAX to complete this partial update.</p>
  <p>Please could someone help with the solution?</p>
