Our public website uses several forms with the BizForm Web Part. I recently tested our site against WCAG 2.0 AA Accessibility Standards, and to meet this standard I need to be able to customize some of the forms output.
For example, I need form fields with instructions to include an aria-describedby="[id]" with the id on the div/paragraph instructions.
I could modify the BizForm ascx, but that doesn't feel like the best way to go about this, especially for updating our Kentico versions in the future.
What would be the best practice approach?
