# Customize the head navigation bar
Since version `1.5.6`, you can add the html element to the top navigation bar, open `app/Admin/bootstrap.php`:
```php
use Encore\Admin\Facades\Admin;
Admin::navbar(function (\Encore\Admin\Widgets\Navbar $navbar) {
$navbar->left('html...');
$navbar->right('html...');
});
```
Methods `left` and `right` are used to add content to the left and right sides of the head, the method parameters can be any object that can be rendered (objects which impletements `Htmlable`, `Renderable`, or has method `__toString()`) or strings.
## Add elements to the left
For example, add a search bar on the left, first create a view `resources/views/search-bar.blade.php`:
```php
```
Then add it to the head navigation bar:
```php
$navbar->left(view('search-bar'));
```
## Add elements to the right
You can only add the `` tag on the right side of the navigation, such as adding some prompt icons, creating a new rendering class `app/Admin/Extensions/Nav/Links.php`
```php
4
7
9
HTML;
}
}
```
Then add it to the head navigation bar:
```php
$navbar->right(new \App\Admin\Extensions\Nav\Links());
```
Or use the following html to add a drop-down menu:
```html
```
