On the mobile version of my website, I chose a drilldown menu layout. This issue arises when creating a mobile menu with multiple tabs. On my website, the main menu and submenu have vertical scrolling that follows the same position. In other words, when I select a bottom tab in the main menu, the submenu appears in the same position as the main menu. As a result, visitors in the submenu have to scroll back up to click the “Back to Main Menu” button, which is located at the top. This causes the main menu to return to the top position as well. I want the main menu and submenu to have independent scrolling, so they do not follow the same position.
