I've got a reasonably simple requirement but can't come up with any appealing ways of presenting it to the user.
To meet the requirement, the user has to be able to choose 1 or more age groups, ranging from 6 to 18. In its most simplest form, it would be a row or grid of 13 checkboxes with the values 6 to 18.
The selection can be completely random, i.e. 7, 10, and 18 so any kind of slider or other selector that would work with a maximum value won't work.
I'd love to hear some ideas on how to make this more appealing to the user.
