If you have not yet created a grid menu, please follow these steps: How do I create tiles in the grid menu?
In the administration menu under Pages & Menu, click on the pencil icon next to your Grid Menu page. In our example, we are editing the “Community page”.
Then select the color palette icon.
Move your mouse pointer over the tile you want to edit and select the pencil icon.
You can change the icon of the tile under Icon. Click on Save to make the changes visible.
Tip: If you do not want to use an icon, you will find the corresponding placeholder at the top of the icon list.
Image allows you to define a custom background image for the tile. In this example, we have removed the icon and title to show only the image. Click Save to preview the image.
If you select inverted for Style, the default background changes to a colored design. Click on Save apply the changes visible.
Under Colors, you can customize the font or background. Check the appropriate box and customize the tile to match your corporate identity. Do not forget to save.
