Is there a way to hide or display elements in the request form based on a item selected in a entitlement table. For example if I have an entitlement table with three items a,b,c. If the user select a, I need to show a text field to get the phone number.

As far as i know it's not possible by default but i did it using javascript block and navigating the dom. I attached an event on the table checkboxes and onclick() i navigate the dom to take the checked elements. Maybe in these days i'll start a discussion with the code.

  Hi Sriranjani,
  at the moment i'm very busy so a discussion where i explain all the contents is not possible for me. The code is attached below, if you have some question, i'll respond.
  My use case was to calculate the total of a column only where the rows(Entitlement) were selected
  
  var t = document.getElementById('YOUR-ENT-TABLE_table');
  var c=0;
  r = t.getElementsByTagName('tr');
  for (var j=0, l=r.length; j<l; j++){
  ce=r[j].getElementsByTagName('td');
  ce[0].onclick=function(){
  c=0;
  r=document.getElementsByTagName('tr');
  for(var k=0; k<r.length;k++){
  if(r[k].className=="Row_Sel"){
  h=r[k].getElementsByTagName('td');
  for(var u=0,n=h.length;u<n;u++){
  if(!isNaN(h[u].innerHTML))
  c+=parseInt(h[u].innerHTML);
  }
  }
  }
  avform.setValue('ANOTHER_VARIABLE',(c*12).toFixed(2));
  };
  }
  what you'll want to do must be programmed inside the function, you could also define a function in another JS block in order to have more char space, damn 500 char limit
  
  Hope it's useful

    Hi @marco sannino,
    I have a simliar query. However, I am not able to extract all the selected rows in the entitlement table when there is a pagination in the entitlement table.
    Example: If I select a row in Page 1 of the entitlement table and when I move to Page 2 of the entitlement table and select a row, I don't get the rows selected from Page 1 using this - "document.getElementsByClassName("Row_Sel")".

      Hi Ganeshram Dharmarajan ,
      since you're working on dom elements(and in js it's right) it's not working because the pagination will exclude the the elements from it. I suggest you to not use impagination if you want to achieve this. I can't imagine a different solution or better you could work adding the selected element to a variable in the form separated by a semicolon and then use it in the workflow parsing it, but depend on what's your goal. Maybe if you explain your needs i can help you.
      
      Regards.

        HI @marco sannino
        
        My requirement: This request form is for the requestor to add roles to the users. So there are few fields which are hidden and it appears when certain roles are selected. So I need to check if the requestor selects any of these roles for the hidden fields to be displayed. Below is my code:
        
        //fields that needs to be hidden
        $(field1).hide();
        $(field2).hide();
        
        //function call when an item is selected
        $(MyEntitlmentTable).change(function(){
        var flagnum=0;
        //function call to get the flag number based on the role selection
        flagnum=getRoles();
        if (flagnum == 1)
        {$(field1).show();
        $(field2).show();
        else
        {$(field1).hide();
        $(field2).hide();
        });
        
        function getRoles()
        {
        var flag=0;
        var roles = [];
        
        // these are the roles for which the hidden fields must be displayed when selected.
        var SigRol= ["RoleA","RoleB","RoleC"];
        
        // extacting the rows selected
        var rows = document.getElementsByClassName("Row_Sel");
        for(var i=0; i<rows.length; i++) {
        var role = rows[i].cells[1].innerText; // extracted the Role from the selected row
        roles.push(role);
        }
        for(var i=0; i<roles.length; i++) {
        for (var j=0; j<SigRol.length; j++){
        if (SigRol[j].trim()==roles[i].trim()) // checking if the selected roles are part of the roles defined in variable SigRol
        {flag=1;} // flag = 1 if the selected role matches with the role defined in variable SigRol
        }
        }
        return flag;
        }
        
        The above code works fine. However, I face issues when I select roles in the following scenarios:
        
        1. When I select roles from page 2 of the entitlement table, the line "var rows = document.getElementsByClassName("Row_Sel");" returns the selected roles from page 2 (ignores the selected roles in Page 1).
        
        2. When I select roles after using the search option. It returns the selected roles that is displayed in that page after the search criteria.
        
        3. Also, when I select the checkbox all, it returns all the roles of Page 1 and the roles present in other pages of the entitlement table is ignored.

        Hello Ganesh,
        
        As i said and you proved my code works only if the elements are displayed. What i can suggest is to create a hidden custom field where on role click the role name will be written in it. After with another js function you parse the field and display what you need.

    Hi,
    I found that your code is useful. I have a question regarding the code below. Is 'YOUR-ENT-TABLE_table' referring to the business source name or the collector name?
    
    var t = document.getElementById('YOUR-ENT-TABLE_table');
    var c=0;
    r = t.getElementsByTagName('tr');
    for (var j=0, l=r.length; j<l; j++){
    ce=r[j].getElementsByTagName('td');
    ce[0].onclick=function(){
    c=0;
    r=document.getElementsByTagName('tr');
    for(var k=0; k<r.length;k++){
    if(r[k].className=="Row_Sel"){
    h=r[k].getElementsByTagName('td');
    for(var u=0,n=h.length;u<n;u++){
    if(!isNaN(h[u].innerHTML))
    c+=parseInt(h[u].innerHTML);
    }
    }
    }
    avform.setValue('ANOTHER_VARIABLE',(c*12).toFixed(2));
    };
    }
    
    Thanks.

      Most likely 'YOUR-ENT-TABLE_table' refers to the variable name of the control type
