You can update the order of how your website Menu and footer displays. Navigate to the Website Builder, click Navigation and then the option you would like to adjust.
You can then click and drag on the menu item you would like to display. You can move this up or down.
If you want to change the parent where the child menu displays, just click the Child Menu and select which Parent this should appear under. Save.
Once you are happy with the changes, you can save at the bottom right corner. The updates will then be published live on the website.
