In the on-line catalogue there is available a function "picture index" . Thanks to it you can browse the offer in the form of photos representing components from separate groups of products.
In order to access to the picture index from any position in the catalogue, you should click the button "PICTURE INDEX" placed at the top of the frame containing groups of products.
Moving through the groups of products using picture index works in the same ways as through the tree index.
To expand a subcategory of a chosen group in the form of photos, it is enough to click on a photo presenting the group. Then it will appear a new layer corresponding to the made choice.
To close the layer with subcategories you should use the sign X placed on this layer.
