Can I change the order of events and products?

All events are ordered by event start date ascending. You have finer control over the listing of products within your events by using the "sort order" attribute for each product. Products will then be sorted in ascending order so a product with a sort order of 1 would show above one with a sort order of 10.

Events are sorted in event start date order ascending. Product groups don't have the concept of an event date so if you want to change the order of your product groups so they appear below other product groups or events (where you have merged events / product group pages), click "Convert To Event" from your product group management menu:

When the product group has been converted to an event, click the event name or select "Edit Event" from your event management menu and change the event date to some point in the future:

You can then convert back to a product group by selecting "Convert to Product Group" from your event management menu.
