Dictionaries define the fixed sets of values available for selection in drop-down list or multi-select properties across your catalog. Instead of allowing free-text entry, dictionary-backed properties constrain input to a predefined list, ensuring data consistency across all products that share the same property. Common scenarios include:

- **Standardized attribute lists** – Maintain a single source of truth for attributes like available sizes or colors so that all products referencing the same property use identical values.
- **Faceted search and filtering** – Consistent dictionary values ensure that storefront filters and search facets work correctly, because variations in spelling or formatting would cause items to appear under separate facet entries.
- **Bulk catalog management** – When a size or color is introduced across a product line, adding it once to the dictionary makes it immediately available to every property that references that dictionary.
- **Data validation** – Restricting a property to dictionary values prevents invalid or inconsistent entries during product creation and import.

Go to **Settings** > **Dictionaries**. The **Dictionary Property Values** page lists all dictionaries defined in your system, the values each one contains, and the catalog entry types that use them.

- **Name column** – Displays the programmatic identifier of the dictionary property (for example, `AvailableSizes`, `AvailableColors`). This name corresponds to the property defined on the meta class that references this dictionary.
- **Values column** – Lists every value currently defined in the dictionary as a comma-separated sequence. For example, `AvailableSizes` contains standard US and international sizes such as *S*, *M*, *L*, *XL*, *1X*, *2XL*, and shoe sizes ranging from *5.5* to *14*. `AvailableColors` contains the full range of color names available for selection on a product, such as *Black*, *Navy*, *Coral Floral*, and *Vintage Gold*. Click into a dictionary to add, edit, or remove individual values.
- **Used by column** – Identifies which catalog entry type or meta class references each dictionary (for example, *FashionProduct*). This helps you understand the downstream impact before modifying the values in a dictionary.
