+### Rollup count as link
+
+When using a rollup field with the **Count** function, you can enable the **"Show count as links"** option to make the displayed count clickable. This allows users to directly access and view the underlying linked records that contribute to the count. Once enabled, the rollup field becomes editable, allowing you to add or modify records in the linked table directly from the rollup field.

+
+Additionally, you can configure "Singular label" & "Plural label" for the rollup field. These labels will be used to display the count in a more user-friendly manner, such as "1 record" or "5 records".
+
+Rollup count as link is available only for the `Count` aggregation function & with `ID` field type selected as the related table field during rollup creation.
+
+<Callout type="info">
+API response for rollup field will always return the count as a number, regardless of whether the "Show count as links" option is enabled or not. If you need to retrieve the linked records, you can use associated `LinkToAnotherRecord` field type instead.
