You can use a variety of different icons for your top level menu items. However, if none of the standard icons is exactly what you're looking for, you can also use your own custom icon. Designing a custom icon, especially one that looks good on the menu bar, requires some knowledge of image file types and access to image editing software.
The requirements for your custom icon are:
Once you have an icon that meets the above requirements, here are the steps to use your custom icon on your menu:
Note you cannot update the icon file to a new image. If you want to use a new icon, upload file with different name.
Note for the mobile site, if the icon has text then it will be scaled tiny and on left side of menu text. If it doesn't have text it will be scaled to fit menu bar width.
In order to look correct and consistent with the other icons on the menu bar, the icon you provide should have transparent areas where the blue of the menu bar can show through the icon. The .GIF and .PNG image formats support transparency, but other image formats do not. For example, if our puppy icon above were saved as a .JPG (no transparency), it would appear on the menu bar as follows:
The menu icon will still function properly, but it doesn't look right, especially when displayed along with the other icons.
