By default, the platform does not have this option. You can use the following Javascript code so the submenu on the BuddyPanel is open by default. 

Please follow the steps below:

    1. Go to BuddyBoss - Theme Options.

    2. Under Custom Codes, enable JavaScript.

    3. Append the following:

document.addEventListener("DOMContentLoaded", function() {
        var subMenu = document.querySelector(".sub-menu");
        subMenu.classList.add("bb-open");
    });

    4. Click Save Changes.

Note: Any modifications are considered as custom work already. Know more about our Support Policy here: https://www.buddyboss.com/support-policy/
