# Add Columns

Configure the fields (columns) to be displayed in the lookup selector. You can also add virtual columns to display data retrieved from DataSources.

**Field-Level Security (FLS) is not currently enforced.** If a user lacks permissions for a specific field, errors may occur. This limitation will be addressed in future updates.
{% endhint %}

### Steps to Configure
