We could create dashboard footer by adding HTML and CSS codes as below:

<!--view/admin/index.ejs-->
<link rel="stylesheet" href="/styles/admin/index.css" />

<section class="Header">
    <div class="menu region">
        <div class="logo"><%= data.pageTitle %></div>
        <form>
            <select name="adminSearch">
                <option>ការងារ</option>
            </select>
            <input type="text" name="q" required placeholder="Search" />
            <input type="submit" value="ស្វែង​រក" />
        </form>
        <div class="logout"><a href="/">ទំព័រ​មុខ</a> | <a href="/logout">ចេញ​ក្រៅ</a></div>
    </div>
</section>

<section class="Main">
