CMS: Changing a Field Type in a Collection

5 min read
Change the type of data you can store in a CMS (Content Management System) collection field by changing the field type. Keep in mind that changing the field type of a field that is connected to page elements can disconnect the elements on your live site. 
If the field type you want to change is connected to elements on your site, rather than changing the field type, consider creating a new field instead. You can paste your existing field's data to the new field. This ensures page elements connected to the existing field remain intact. 

Effects of changing a field type

Consider the effects of changing a field type to ensure your live site content remains connected and functioning as expected. Since field types determine the type of data you can keep in each field, changing them can disconnect any of their connected page elements. This can result in page elements displaying no content at all or not working as expected. 

Other problems that can occur as a result of changing a field type:
  • If you have dynamic pages that use the field as a filter, the links to the pages may no longer work. 
  • If you have a dataset that uses the field to filter or sort content, the connection may break between the elements and the collection.

In your collection, if you have fields with values that do not match the field type, a Warning icon appears to let you know. If available, you can click to convert the value so it matches the correct field type format.

Keep in mind, if you make a mistake and need to revert your collection to a previous version, you can do so with Backups
