# cp.ui.DisclosureTriangle

Disclosure Triangle UI Module.

This represents an `hs.axuielement` with a `AXDisclosureTriangle` role.
It allows checking and modifying the `opened` status like so:

```lua
myButton:opened() == true			-- happens to be opened already
myButton:opened(false) == false	-- update to unopened.
myButton.opened:toggle() == true	-- toggled back to being opened.
```

You can also call instances of `DisclosureTriangle` as a function, which will return
the `opened` status:

```lua
myButton() == true			-- still true
myButton(false) == false	-- now false
```
