title: Make DisclosureGroup non expanable
body: <p>I'm adding one DisclosureGroup inside another DisclosureGroup
  I want the second Disclosure group to be non expandable(Remove the ability to expand).
  Is that possible or is there a better way to achieve this?</p>
  <pre><code>@discardableResult
  private func expand(key: String) -&gt; Binding&lt;Bool&gt; {
      return Binding&lt;Bool&gt;(
          get: { expanded.contains(key) },
          set: { isExpanding in
              if isExpanding {
                  expanded.insert(key)
              } else {
                  expanded.remove(key)
              }
          }
      )
  }
  
  
  DisclosureGroup(isExpanded: expand(key: &quot;Incomplete&quot;)) {
      ForEach(Array(array), id: \.self) { key in
          if let innerArray = innerArray {
              // Make non expanable
              DisclosureGroup {
                  ForEach(Array(tasks.enumerated()), id:\.1.title) { (index, check) in
                      // Content
                  }
              } label: {
                  // Header
              }
          }
      }
  } label: {
      // Header
  }
