People Picker Input box control behaves differently in Default.aspx & ClientWebPart.aspx

Question

Have a code that searches group names using the people picker app. I write the same code one on default.aspx and the other in a client webpart page.But, both show results quiet differently. For example i would want the expand and shrink functionality of the input box in a Default.aspx work the same way in a client webpart.aspx page as well.

My code is as follows:

Default/ClientWebpart.aspx

a div element: id="peoplePickerGroupDiv" style="height: 20px"

Script file:

$(document).ready(function () {

initializePeoplePickerForGroup();

});

function initializePeoplePickerForGroup() {

// Create a schema to store picker properties, and set the properties.
var option = {};
option['PrincipalAccountType'] = 'SPGroup';
option['SearchPrincipalSource'] = 15;
option['ResolvePrincipalSource'] = 15;
option['AllowMultipleValues'] = true;
option['MaximumEntitySuggestions'] = 50;
option['Width'] = '280px';

SPClientPeoplePicker_InitStandaloneControlWrapper('peoplePickerGroupDiv', null, option);

}

Result on CWP.aspx:

Result on Default.aspx:

Could anyone guide me to known why there is a difference and how could i possibly solve it?

It looks like you are missing the CSS file that has the CSS for the people picker control, you can inspect it in both your cases to see if this is truly the case.

If so, you can try adding the following in your client web part, is some default code that is automatically added but maybe you've deleted it:

// Set the style of the client web part page to be consistent with the host web.
            (function () {
                var hostUrl = '';
                var link = document.createElement('link');
                link.setAttribute('rel', 'stylesheet');
                if (document.URL.indexOf('?') != -1) {
                    var params = document.URL.split('?')[1].split('&');
                    for (var i = 0; i < params.length; i++) {
                        var p = decodeURIComponent(params[i]);
                        if (/^SPHostUrl=/i.test(p)) {
                            hostUrl = p.split('=')[1];
                            link.setAttribute('href', hostUrl + '/_layouts/15/defaultcss.ashx');
                            break;
                        }
                    }
                }
                if (hostUrl == '') {
                    link.setAttribute('href', '/_layouts/15/1033/styles/themable/corev15.css');
                }
                document.head.appendChild(link);
           })();
