I'm trying to create a custom collapsible view. The code works but in Collapsible<Content: View> the VStack has strange behavior: the elements overlap when the component is closed.
To note this, try disable clipped() as shown in the image.
Is it a bug or something so stupid that I am not noticing? Thanks in advance
FIXED CODE:
struct Collapsible<Content: View>: View {
var label: String
var content: () -> Content
init(label: String, @ViewBuilder _ content: @escaping () -> Content) {
self.label = label
self.content = content
}
@State private var collapsed: Bool = true
var body: some View {
VStack(spacing: 0) {
Button(action: {
withAnimation(.easeInOut) {
self.collapsed.toggle()
}
}, label: {
HStack {
Text(label)
Spacer(minLength: 0)
Image(systemName: self.collapsed ? "chevron.down" : "chevron.up")
}
.padding()
.background(Color.white.opacity(0.1))
}
)
.buttonStyle(PlainButtonStyle())
self.content()
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: collapsed ? 0 : .none, alignment: .top) // <- added `alignment` here
.clipped() // Comment to see the overlap
.animation(.easeOut)
.transition(.slide)
}
}
}
struct CollapsibleDemoView: View {
var body: some View {
VStack(alignment: .leading, spacing: 0) {
Collapsible(label: "Collapsible") {
Text("Content")
.padding()
.background(Color.red)
}
Spacer(minLength: 0)
}
.padding()
.frame(maxWidth: .infinity, maxHeight: .infinity)
}
}
