dropdown list(Multiselect)it is not opening in Telerik UI MVC

Sometimes, CSS or JavaScript conflicts between Telerik UI components and your custom scripts or styles can prevent elements from displaying correctly. Try to disable custom styles or scripts to see if the dropdown starts working.

Open your browser developer tools (F12) and check the JavaScript console for any errors or warnings that might indicate what's preventing the dropdown from opening.

Then verify that all necessary JavaScript files for Telerik UI and jQuery are correctly loaded. Sometimes, version upgrades can cause conflicts or missing references. Ensure you have included the correct versions of the Telerik scripts and jQuery.

You may need to review the Telerik UI release notes between the trial version (2022.1.119.545) and the licensed version (2022.2.510.545). There might be breaking changes or fixes related to dropdown behavior that could be causing this issue. Pay special attention to any changes in how the dropdown components are initialized or interact with jQuery.
