We have developed a more flexible solution that allows users to change their age group and course options without restrictions, except for event options. For instance, when a user is currently viewing the "8 Under" category and the "25 Yard Free" event, we no longer lock the age group options like "9-10" or "11-12," as we did before. In the past, you had to change to a valid event first before switching age groups, which was cumbersome. Now, you can freely select the "9-10" age group, and the system will automatically adjust the event for you.
