# Editing a group

To edit a group, hover your mouse over the group you want to edit, and click on the **Edit** button. You’re then taken to the group editing screen where you can choose Group Options or Options Mapping. 

#### Group Options

To add group options:

1. Click on the **Add Options** link and enter a name for the option. 
2. Click on the **Add Item** link and enter an item name — for example, voice (male or female) and length (short or long). 

#### Options Mapping 

Once the options are set up, you need to assign each item to an experiment. To do this you need to:

1. Click on the **Options Mapping** link. This will show you a column for each option and all the combinations of items. 
2. Use the drop-down menus to assign the experiment to run when each option combination is selected.
