Form Block: Conditional Logic For "Other, Please Specify."

@shiDMV The javascript code below should work for you. 

Javascript

(function(){

  // The value of the "id" HTML attribute of the parent HTML element
  var PARENT_ID = 'select-61719a1c-6980-4b16-b86c-5a7ccff1e8e5-field';

  // The value which will determine the visibility of the DEPENDENT_ID element
  var PARENT_VALUE = 'Other';

  // The value of the "id" HTML attribute of the child HTML element.
  // This field will hide/show depending on the PARENT_VALUE
  var DEPENDENT_ID = 'text-48e31159-ed89-4857-9813-092474be4290';


  /*********************************************************************

  // Initialize after the page has been loaded
  if (document.readyState === 'complete') {
    init();
  } else {
    document.addEventListener("DOMContentLoaded", init, false);
  }

  function init() {
    // Load jQuery if not loaded
    if(!window.jQuery) { return loadJquery(init) }

    // Assign jQuery to a variable
    var $ = jQuery;

    // Get the parent element 
    var $parentField = $('#' + PARENT_ID);

    // Get the dependent element
    var $dependentField = $('#'+ DEPENDENT_ID);

    // Hide the text field on page load
    $dependentField.hide();
  
    // Show or hide the dependent field based on the PARENT_VALUE
    $parentField.on('change', function(evt){
      if(evt.currentTarget.value == PARENT_VALUE ) {
        $dependentField.slideDown();
      } else {
        $dependentField.slideUp();
      }
    });
  }

  function loadJquery(init) {
    var s = document.createElement('script');
    s.src = 'https://code.jquery.com/jquery-3.6.0.min.js';
    s.integrity = 'sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=';
    s.crossorigin = 'anonymous';
    s.onload = init;
    document.body.appendChild(s);
  };
})()

Make sure to place this between <script> tags. For example:

<script>
  // Place JS Code Here
</script>
