Difficult to select multiple rights shells from the grouping page

[bonniegee]

It is difficult to select multiple rights shells on the grouping page. Because the field renders as a "select multiple" HTML attribute, a user must know how to select multiple options in their operating system (e.g., holding down the command key on a Mac).

There are 3 possible solutions:

• Adding help text that indicates that multiple options can be selected at once and directs the user how to select multiple options
• Changing the form widget from SelectMultiple to CheckboxSelectMultiple
• Customizing the SelectMultiple (or CheckboxSelectMultiple) widget

Changing the form widget from SelectMultiple to CheckboxSelectMultiple is the preferred option. If that solution does not work, the other solutions should be evaluated.
