There is a button in the CaterQuotes catalogue called "Match". It allows the user to find any items that match the selected items specification. This is very useful for comparing products and finding alternatives.
To use this feature, search for and select an item and click on the match button at the top or right click the item and select match from the menu.
The catalogue will refresh and any other items with the same specification will now be listed as results. If no results are found, you will need to widen the scope of the search by deselecting some filters on the left.
