This topic describes available configuration options for the user interface, with the purposes of enhancing performance and improving the user experience.
You should model the catalog using category hierarchies to avoid having too many items in the same category.
With too many items in a category, it is hard for the user to find an item using the catalog UI components. Also, the catalog UI may become slow, and handling the items consumes a large amount of system resources, both server side and client side.
If a category contains more than a certain number of items, default 2000, a simplified UI mode is used, disabling certain features to try to stay responsive. Sorting is disabled, as are the grouping of variations into their parent products and bundling/packaging of items into a bundle/package.
When simplified UI mode is used, a message appears in the catalog listing: This category listing contains too many items. Some
features have been disabled to improve performance.
Configure the threshold for using the simplified mode via the SimplifiedCatalogListingThreshold appSetting:
<appSettings> <add key="SimplifiedCatalogListingThreshold" value="1000" /> </appSettings>
