dropdown-toggle does not work

After signing in into website, on right-coner of header shows personal information, but dropdown table does not work.
Could you show me the way fixing this issue?

<div class="author-edit" id="user_avatar_container">
                    <span class="author-avatar image" id="user_avatar_thumbnail">
                                            </span>
                    <div class="edit-info-avatar">
                        <a href="void(0);">
                            Upload New Avatar                        </a>
                        <a href="void(0);">Change Password</a>
                        <a href="void(0);">Change Profile</a>
                    </div>
<!--                    <span class="et_ajaxnonce" id="--><!--"></span>-->
                </div>
