Replace a Service Catalog form script with a widget

You can use widgets in Service Portal to replace UI Macros. If your Service Catalog form includes a UI Macro that references other fields or variables on the form, you can create a widget to hold reusable code and embed it within the Service Catalog form. Use special syntax to access any variable fields on the form.

Before you begin

Role required: admin or sp_admin


  1. Create a widget that performs the action you would like to use in catalog item forms. See step 7 for a simple example widget that accesses another variable on the form.
  2. Open a catalog item that previously used a UI Macro or other reusable component not supported in Service Portal.
  3. In related lists, add a new variable to the catalog item.
  4. Configure the variable form to add the Widget field.
  5. In the Type field, select Macro.
  6. In the Widget field, select a widget that performs the desired action.
  7. (Optional) Use the $ or $ syntax in the embedded widget to access the catalog item values.
    This example shows how to modify the value of a single-line text variable with the name color associated with the catalog item.
    Widget HTML Template
      Data from catalog variable:  
      <h1>{{ }}</h1>  
    Widget client script
    function($scope) {  
         var c = this;  
         //Watch for changes in the color variable  
         $scope.$watch(function () {  
              return $'color');  
         }, function (value) {  
         //Update local data object with data from variable   = value ? 'Content of color variable: ' + value : '';  
    You can use the following to access variable or catalog item fields:
    • $ The g_form instance on the form. You can use all supported g_form methods described in Service Portal and client scripts. For example, g_form.setValue('variable_name', 'new value');.
    • $ The object that represents the variable.
    When you open the catalog item in the Service Portal, the embedded widget accesses the variable fields associated with the catalog item.

    The input to the variable displays in the embedded widget.
