Hi Ziad,

Dynamic checkboxes are possible, however to get any sort of routing on them or to have them show in the saved form might be a bit of a challenge. In the code I have created a function that you can call upon on form load / table add row and table delete row. Please note thought that this is not a complete solution for you. i.e. there are a few bugs with the code and how it operates. This is merely to get you on the right track.

//Function to call on form load / add-row / delete row
//readTableId as q17 or your table number that you want to read from
//readTableInputCSS field is the css field you want to read from. This is only set to read one field currently
//checkbox field id just number - ie. qID of field is q36 then just input 36 here
function UpdateDynamicCheckbox(readTableID, readTableInputCSS,checkboxID,outputTableID){ 
  //set variables 	
  var tID = readTableID;
  	var oTID = outputTableID;
  	var cID = checkboxID;
  	var inVal = readTableInputCSS;
    var i = 1;
  	//used to update each row in output table
  $('#'+oTID+'.cf-table-block tbody tr').each(function(){
    var cnum = 0;
    //get checkbox element id
  	var element = document.getElementById('Field'+cID+'('+i+')');
    //clear the contents to add new
    element.firstChild.innerHTML = "";
	var html;
  //loop through input table to get checkbox variables
  $('#'+tID+'.cf-table-block tbody tr').each(function(){
    //find css of input field as specified - can add more here if required
    var inValue = $(this).find('.'+inVal+' input').val();
    //if index is less than table length and input value is not blank
    if (cnum < ($('#'+tID+' tr').length-1) && inValue != ""){ 
      //set display value
      var display = inValue;
      //set value and replace spaces with underscore
      var value = inValue.replace(" ", "_");
      //create html
      html = '<span class="choice"><input name="Field'+cID+'('+i+')" id="Field'+cID+'('+i+')-'+cnum+'" type="checkbox" value="'+value+'" vo="e" data-parsley-class-handler="#Field'+cID+'\('+i+'\)" data-parsley-errors-container="#Field'+cID+'\('+i+'\)" data-parsley-multiple="Field'+cID+'('+i+')"onclick="handleChkbxClick(this);"><label class="form-option-label" for="Field'+cID+'('+i+')-'+cnum+'">'+display+'</label></span>';
   	  //insert html at end of child element
      element.firstChild.insertAdjacentHTML("beforeEnd", html);
      //increase for row count
      cnum++;
		}
  });
    //for second row in output table
  i++;
});
}
//custom function that will be added to created checkbox
function handleChkbxClick(cb) {
  //get checkbox value
  var value = cb.value;
  //get checkbox name
  var name = cb.name;
  //run regular expressions to get the row count
  var rowNumIn = /[(]\d[)]/.exec(name);
  var rowNum = /\d/.exec(rowNumIn);
  //find email in supplier table for specified index number
  var email = $('#q35 tbody tr:nth-child('+rowNum+')').find('.email input').val();
  //loop through parts table
  $('#q17.cf-table-block tbody tr').each(function(){
   //if value in parts table matches value of selected checkbox
	if( $(this).find('.qty input').val() == value)
    {//get the current email list of the row
      var current = $(this).find('.emailList textarea').val() || "";
      if(cb.checked)//check to make sure checkbox is checked
  	{ //if length of email list is > 3 then append list, else just insert email
      if (current.length > 3){$(this).find('.emailList textarea').val(current +"; "+email);}
      else {$(this).find('.emailList textarea').val(email);}
    }
    else
    { //if unchecked checkbox, replace email with blank.
      var remove = current.replace(email, "");
      $(this).find('.emailList textarea').val(remove);
    }
  }
  }); 
}
$(document).ready(function(){
 UpdateDynamicCheckbox('q17','qty','36','q35'); 

  $('.cf-table-add-row').click(function(){
     UpdateDynamicCheckbox('q17','qty','36','q35');              
	});
   $('#q17.cf-table-block tbody').on('click','.cf-table-delete',function(){
     UpdateDynamicCheckbox('q17','qty','36','q35');              
	});
});

The code will read one input field in one table and populate a checkbox in the second table with its Value.

When one of the dynamic checkbox's are selected the idea behind the code is that it will append a multi-line text field with the email address. You should be able to route and generate custom emails for your parts this way.

Just make sure you update the CSS classes and field ID numbers accordingly.

Any questions let me know.
