Column Chooser option in ALM allows users to select only the columns that the user would like to see in their view. Rest of the columns will be hidden from the user view. Column chooser option is available in requirements, Test Lab, Test Runs and Defects module.
For choosing only the necessary columns, a user has to click the "Column Chooser" button.
The Column Chooser dialog opens for the user to choose the necessary columns. There are only 4 columns that are visible to the user at the moment and can be added by the user.
Users cannot unselect everything from their view as "Name" field will always be there under "Visible Columns". Select any field and click the ">" button. The selected field moves to visible columns list.
After selecting the relevant columns, press "OK". You will be able to see the selected columns in the view. In this case "Prioirty" is added to the user view as shown below.
