When the customer's mouse hovers over a logo or image, the rest of the product will fade out. When the customer clicks on an image, the question panel for this specific image will be displayed. This can be practical if you have a complex product. You should turn it off for elements that aren't customizable like a background or shadow.
The focusable checkbox has been activated for the 'pedals' image.
The image will automatically be highlighted when the customer opens a question related to it. This can help the customer to understand which part of the product he is customizing.
When hovering over any part of a focusable group, every part of the group will be highlighted. Select the group you wish to highlight in the dropdown menu under Display Settings in the answer panel (right panel).
Select which group you force to highlight from the dropdown menu. Here, the 'highlight group' is 'Handlebar.'
