Multiple checkbox component - using

Will I find an example of using the Multiple checkbox component somewhere?
(e.g. reading each properties checkboxes and displaying their properties in another component)

Are you looking for CheckBoxList?

Yes, thank you.

But, could you give an example, how to pass to e.g Textarea, the 'Text' property for 'Checkbox' with the value 'x'?

I would be grateful.
