Is your feature request related to a problem?

It's more intuitive and convenient to use data binding style api.

Is it possible to construct a solution with the existing API?

Not available.

Describe the solution you'd like to see.

add an api similar to NewAccordionWithData(data binding.StringList).

What data does Accordion work with? Our data binding API is for just that - user data.

If we attach it to a string list won't it just create a load of empty accordion items with the titles set?

It's my fault for issuing an immature idea.

Sorry to bother.
