Hi @premphalin ,

I think you're either using an old version of the select_page_template field, in which case I recommend you upgrade to the latest:

<!-- Select template field. Used in Backpack/PageManager to redirect to a form with different fields if the template changes. A fork of the select_from_array field with an extra ID and an extra javascript file. -->
  <div @include('crud::inc.field_wrapper_attributes') >

    <label>{{ $field['label'] }}</label>
    <select
        class="form-control"
        id="select_template"

        @foreach ($field as $attribute => $value)
            @if (!is_array($value))
            {{ $attribute }}="{{ $value }}"
            @endif
        @endforeach
        >

        @if (isset($field['allows_null']) && $field['allows_null']==true)
            <option value="">-</option>
        @endif

        @if (count($field['options']))
            @foreach ($field['options'] as $key => $value)
                <option value="{{ $key }}"
                    @if (isset($field['value']) && $key==$field['value'])
                         selected
                    @endif
                >{{ $value }}</option>
            @endforeach
        @endif
    </select>

    @if (isset($field['hint']))
        <p class="help-block">{!! $field['hint'] !!}</p>
    @endif
  </div>

                window.location.href = strip_last_template_parameter(current_url)+'?template='+new_template;
            }

            function strip_last_template_parameter(url) {
                // if it's a create or edit link with a template parameter
                if (url.indexOf("/create/") > -1 || url.indexOf("/edit/") > -1)
                {
                    // remove the last parameter of the url
                    var url_array = url.split('/');
                    url_array = url_array.slice(0, -1);
                    var clean_url = url_array.join('/');

                    return clean_url;
                }

                return url;
            }

            jQuery(document).ready(function($) {
                $("#select_template").change(function(e) {
                    var select_template_confirmation = confirm("@lang('backpack::pagemanager.change_template_confirmation')");
                    if (select_template_confirmation == true) {
                        redirect_to_new_page_with_template_parameter();
                    } else {
                        // txt = "You pressed Cancel!";
                    }
                });

            });
        </script>
    @endpush

Or you're using Backpack/Demo as a starting point for your project (which had this bug), which is not recommended. Take note it's always better to start from scratch. Unless you know what you're doing, in which case go ahead :-)

Cheers!

Also, just pushed a fix that forces this new field, so that people don't accidentally forget to upgrade it. I think that's more future-proof. So from now on, a composer update should make PageManager use the field from the PageManager package instead of _the user's /vendor/backpack/crud/field/``` folder.

Fix here: 9e698cf

Thanks, cheers!
