 At least, you need to have Bootstrap 5 or higher version. The code below will insert Default toggle button. Actually, it is checkbox. < input type ="checkbox" class ="btn-check" id ="default" autocomplete ="off" > < label class ="btn btn-outline-success" for ="default" >Default</ label > And also you can change the color of button by label class.

Javascript - jQuery - Make menu item Active automatically

There is, as minimum, two ways how to add 'active' class to menu item, to highlight it. First one is on backend side. Second one is on frontend side. Now, I talk about variant with frontend side. So, I choose javascript to decide to add 'active' class to menu item or not. There is a code for this: var pathName = window.location.pathname; // Iterate through each anchor tag within list items $("ul li a").each(function () { // Check if the href attribute matches the current URL if ($(this).attr("href") == pathName) { // If there is a match, traverse up the DOM hierarchy to find the corresponding list item $(this).parents('li').each(function () { // Add the 'active' class to highlight the menu item $(this).addClass("active"); }); } }); This script essentially loops through all anchor "a" tags within list items "li" in the specified unordered list "ul".

Symfony - How to fix Circular Reference

 A circular reference in Symfony typically occurs when there's a loop in the dependency injection graph. It means that one service depends on another service, which in turn depends on the first one, creating an infinite loop. Check Your Service Definitions: Review your service definitions in the services.yaml or other configuration files. Look for any circular dependencies. A circular reference often occurs when Service A depends on Service B, and Service B depends on Service A. Use Setter Injection: Instead of injecting dependencies through the constructor, use setter injection. In Symfony, you can use setter injection by creating setter methods in your services and injecting dependencies through these methods after the service is instantiated. Lazy Loading: Consider using lazy loading for dependencies. Symfony allows lazy loading of services, which means that the actual instantiation of a service is delayed until it's actually used. You can enable lazy loading for a service b...
