Thanks for pointing out that thread. Makes sense, though it seems like accessibilityValue is used more for numeric values.

Use only when the label of the element

 differs from a value. For example: A volume slider has a label of "Volume", but a value of "60%".

Is accessibilityValue a better place for "expanded/collapsed" than adding it to the accessibilityLabel? Would it make more sense to put it in the accessibilityLabel if there is an arrow visually present that changes state? This way "expanded/collapsed" would be kind of like the alt text for the arrow which changes state?

Here are 2 screenshots showing the expanded/collapsed buttons.

My past response was blocked due to using images in the email. Hopefully this will go through now.

Does UIAccessibility include the ability to set the state of a button which expands and collapses a sub menu? Something like aria-expanded=true/false? Would this info have to be placed in the accessibility hint and changed dynamically? Something like "Expands the sub menu" and "Collapses the sub menu"?

Same sort of question for a button which expands and collapses to show/hide additional text information on the screen?

Thanks!
