# Column filter dialog box

The Column filter dialog box allows you to perform single column filtering on clinical data values. You can filter on any one column at a time, except for the columns for the review states, site, subject, and visit.

- Columns that contain entered values are filtered by the normalized value.
- For each column you filter, you can select up to five filtering criteria that are appropriate for the column type (for example, numeric, case-insensitive alphanumeric, or date).
- Column filtering is applied only in the current view. All column filtering selections are lost when you navigate away from the current view.
