8.2 Prompting for values
prompt-with-list should handle the majority of cases. The simplest form just passes a list to the function and expects a single item to be returned.(prompt-with-list '(:red :yellow :blue) "Select a color:")

You can also specify the interaction style that you would like for your dialog, which can be any of the interactions accepted by a choice. The specification of the interaction style to this choice is made using the keyword argument:interaction:
(prompt-with-list '(:red :yellow :blue) "Select a color:" :interaction :multiple-selection)By default, the dialog is created using a list-panel to display the items, but the keyword argument
:choice-class can be specified with any choice pane. Thus, for instance, you can present a list of buttons.(prompt-with-list '(:red :yellow :blue) "Select a color:" :interaction :multiple-selection :choice-class 'button-panel)

Finally, as with any of the prompting functions, you can specify additional arguments to the pane that has been created in the dialog. Thus to create a column of buttons instead of the default row, use:
(prompt-with-list '(:red :yellow :blue) "Select a color:" :interaction :multiple-selection :choice-class 'button-panel :pane-args '(:layout-class column-layout))
