If you look your inspect elements of browser each item have own class and the list element have icon (i) element class with pseudo element that you can use css to set other icon. Example

Also why don't you see how other components have done that?

Talking about installation without modification and i am not sure if you have done modification and how your menu elements source look like.

So, I tried to set an icon for a menu value:

My custom_newsfeed.php has this part, I removed the right-angle icon

<?php                        
foreach ($menus as $name => $menu) {
	$section = 'menu-section-'.OssnTranslit::urlize($name).' ';
	$items = 'menu-section-items-'.OssnTranslit::urlize($name).' ';
	
	$expend = '';
	$icon = "";
	if($name == 'links'){
		$expend = 'show';
		$icon = "fa-newspaper";
	}
	if($name  == 'groups'){
		$icon = "fa-users";
	}
	    if($name  == 'profile'){
        $expend = 'show';		
    }
	$hash = 'nm'.md5($name);
    ?>

And my ossn_print.php this:

        $language = $user->language;
    if ($language === 'de') {
        ossn_register_menu_item('newsfeed', array(
            'name' => 'useful:links',
			'text' => '<i class="fas fa-lightbulb"></i> ' . ossn_print('coming:out'),
            'parent' => 'useful:links',
            'href' => ossn_site_url("p/2187/tipps-fur-dein-coming-out"),
        ));
    } else {
        // fallback oder explizit englisch
        ossn_register_menu_item('newsfeed', array(
            'name' => 'useful:links',
            'text' => ossn_print('coming:out'),
            'parent' => 'useful:links',
            'href' => ossn_site_url("p/2188/coming-out-advice"),
        ));
    }

But how can I delete the right angle on the menu item?

thank you, it works!!!

Okay, here we go

1. rename your own newsfeed.php to custom_newsfeed.php
   This will prevent it being replaced by the theme and make it stay in memory

2. remove the callback and its function

3. Instead, we're using this hook now:

   ossn_add_hook('halt', 'view:themes/' . ossn_site_settings('theme') . '/plugins/default/menus/sections/newsfeed', 'com_SidebarRearrange_plugin_replace');

And this hook function

function com_SidebarRearrange_plugin_replace($hook, $type, $return, $params) {
   return ossn_plugin_view('menus/sections/custom_newsfeed', $params);
}

Oops, tried to post the cache issue close before your post - but it seems to be dropped..

But hold on - I'll post a new solution soon

Thank You!

It works when cache is disabled but as soon as I enable the cache, the newsfeed.php is ignored again

If I disable the cache, it is working again 😅

this is my ossn_com, I removed a few lines to make it shorter

            'href' => $user->profileURL(''),
			'section' => 'profile',
        ));
		
    
		
        ossn_register_menu_item('newsfeed', array(
            'name' => 'profileviews',
            'text' => ossn_print('profileviews'),
            'parent' => 'profile',
            'href' => ossn_site_url("profileviews"),
        ));
    }
}

function com_SidebarRearrange_plugin_reload($event, $type, $params) {
   ossn_register_plugins_by_path(ossn_route()->com . 'SidebarRearrange/plugins/');
}

// Callback zur Initialisierung
ossn_register_callback('ossn', 'init', 'sidebar');

In the newsfeed.php I added

if($name == 'profile'){
	$expend = 'show';
	$icon = "fa-newspaper";
}

I'm sorry, I haven't had in mind that the loading order of plugins is system->components->theme. In other words: Theme plugins have the highest priority and can not be replaced by component plugins that easy way. But we can use a callback to force a reload of your own component's plugins again. In your com file add this line right after

if ($user) {

ossn_register_callback('menu', 'section:before:view', 'com_SidebarRearrange_plugin_reload');

Then, somewhere at the end of your com file add the accompanying new function like

function com_SidebarRearrange_plugin_reload($event, $type, $params) {
   ossn_register_plugins_by_path(ossn_route()->com . 'SidebarRearrange/plugins/');
}

Check your log again - your own newsfeed.php will be loaded now. (And don't use echo in general for debugging Ossn)

I placed error_log("Test: Sidebar Menu loaded"); at the beginning of the newsfeed.php in component folder, but when reloading the website or triggering the menu, nothing happens

Also tried with echo "Test: Sidebar Menu loaded"; - nothing - so the file is ignored

Because I did what you said, add 'section' => 'dominik', and then change newsfeed.php in my component folder to

        if($name == 'profile'){
    $expend = 'show';
    $icon = "fa-user";

}

but it just adds a new section which is not expanded and has no icon, so I guess the newsfeed.php in my component folder is not recognized?

I am a little bit confused

When I add it like this:

function sidebar() {	
    ossn_extend_view('css/ossn.default', 'css/sidebar');
	
    // Überprüfen, ob der Benutzer eingeloggt ist
    $user = ossn_loggedin_user();
    
    if ($user) {
        ossn_register_menu_item('newsfeed', array(
            'name' => 'home',
            'text' => ossn_print('home'),
            'href' => ossn_site_url(),
            'parent' => 'profile',
            'priority' => 0,
        ));
		
        ossn_register_sections_menu('newsfeed', array(
            'name' => 'profile',
            'text' => ossn_print('meinprofil'),
            'href' => $user->profileURL(''),
			'section' => 'profile1',

			
        ));

Do i have to change every other"parent" in ossn_register_menu_item from profile to profile 1?

Like this?

function sidebar() {	
ossn_extend_view('css/ossn.default', 'css/sidebar');

// Überprüfen, ob der Benutzer eingeloggt ist
$user = ossn_loggedin_user();

if ($user) {
    ossn_register_menu_item('newsfeed', array(
        'name' => 'home',
        'text' => ossn_print('home'),
        'href' => ossn_site_url(),
        'parent' => 'profile1',
        'priority' => 0,
    ));
	
    ossn_register_sections_menu('newsfeed', array(
        'name' => 'profile',
        'text' => ossn_print('meinprofil'),
        'href' => $user->profileURL(''),
		'section' => 'profile1',

		
    ));
	
    ossn_register_menu_item('newsfeed', array(
        'name' => 'friends',
        'text' => ossn_print('friends'),
        'parent' => 'profile1',
        'href' => $user->profileURL('/friends'),
    ));
