I have an app written in Forge which uses Custom UI and has a series of radio boxes. When the page visitor selects a radio box, I want to store the value(s) they selected, and to show them that they have now voted, and which option they selected. Ideally I'd also like to show the user how many other respondents picked the same value(s), and allow the page owner to have an overview of all responses.
Is there a way to store this? In Forge UI there's a function called useContentProperty which seems to do what I need, but is there an equivalent in Custom UI?
