Configuration
Section – Style
You can customize the appearance of section by applying different styles using the modifier. This modifier can be used globally or per section. The library already contains the , and styles.scrollViewSectionStyle(_ style: any ScrollViewSectionStyle)
.plain
.grouped
.insetGrouped
In the following example the first uses the style because it is set as part of the component but the second uses style. This is because under the hood the modifier is using . This means that you can use this modifier to set a global style for the entire application.ScrollViewSection
.grouped

EnvironmentKey
import ScrollViewSectionKit
struct ContentView: View {
var body: some View {
ScrollView {
VStack(spacing: 0.0) {
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
.scrollViewSectionStyle(.insetGrouped)
}
}
.scrollViewSectionStyle(.grouped)
.scrollViewSectionBackgroundColor(.clear)
.background {
Color(uiColor: UIColor.systemGroupedBackground)
.ignoresSafeArea()
}
}
}
It should look like this ⬇️
Section – Background Color
You can customize the appearance of section by applying different background colors using the modifier. This modifier can be used globally or per section.scrollViewSectionBackgroundColor(_ color: Color)
In the following example the first uses the background color because it is set as part of the component but the second uses background color. This is because under the hood the modifier is using . This means that you can use this modifier to set a global style for the entire application.ScrollViewSection
.blue.opacity(0.28)

.orange.opacity(0.28)

ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
} header: {

}
ScrollViewSection {
Text("This is a 1st row.")

.scrollViewSectionBackgroundColor(.blue.opacity(0.28))
.background {
Color(uiColor: UIColor.systemGroupedBackground)
.ignoresSafeArea()
}
}
}
It should look like this ⬇️
Row – Background Color
You can customize the appearance of row by applying different background colors using the modifier. This modifier can be used per section or per row.scrollViewRowBackgroundColor(_ color: Color)
In the following example the second row of the first section uses the background color because it is set as part of row. The first row of the second section, on the other hand, uses background color because the entire section uses this modifier and the last row of the second section uses the background color..blue.opacity(0.28)
.green.opacity(0.28)
.orange.opacity(0.28)
import ScrollViewSectionKit
struct ContentView: View {
var body: some View {
ScrollView {
VStack(spacing: 0.0) {
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
.scrollViewRowBackgroundColor(.blue.opacity(0.28))
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
.scrollViewRowBackgroundColor(.orange.opacity(0.28))
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
.scrollViewSectionStyle(.insetGrouped)
.scrollViewRowBackgroundColor(.green.opacity(0.28))
}
}
.scrollViewSectionStyle(.grouped)
.scrollViewSectionBackgroundColor(.clear)
.background {
Color(uiColor: UIColor.systemGroupedBackground)
.ignoresSafeArea()
}
}
}
It should look like this ⬇️
Row – Insets
You can also customize the appearance of row by applying different row insets using the modifier. This modifier can be used per section or per row.scrollViewRowInsets(_ insets: EdgeInsets?)
In the following example the whole first section uses row insets because the entire section uses this modifier. The first row of the second section, on the other hand, uses row insets because just this one row uses this modifier and the last row uses default row insets.EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0)
EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0)
import ScrollViewSectionKit
struct ContentView: View {
var body: some View {
ScrollView {
VStack(spacing: 0.0) {
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
.scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
ScrollViewSection {
HStack(spacing: 10.0) {
Image(systemName: "person.fill")
.resizable()
.scaledToFit()
.frame(width: 20.0, height: 20.0)
Text("This is a 1st row.")
}
.scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
Text("This is a 2nd row.")
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
.scrollViewSectionStyle(.insetGrouped)
}
}
.scrollViewSectionStyle(.grouped)
.scrollViewSectionBackgroundColor(.clear)
.background {
Color(uiColor: UIColor.systemGroupedBackground)
.ignoresSafeArea()
}
}
}
It should look like this ⬇️
Row – Separator Insets
In the previous example we adjusted the row insets but the separators still use the default insets. We can change this by using modifier. This modifier can be used per section or per row.scrollViewRowSeparatorInsets(_ insets: EdgeInsets?)
In the following example the whole first section uses row separator insets because the entire section uses this modifier. The first row of the second section, on the other hand, uses row separator insets because just this one row uses this modifier and the last row uses default row insets.EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0)
EdgeInsets(top: 0.0, leading: 70.0, bottom: 0.0, trailing: 0.0)
import ScrollViewSectionKit
struct ContentView: View {
var body: some View {
ScrollView {
VStack(spacing: 0.0) {
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
.scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
.scrollViewRowSeparatorInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
ScrollViewSection {
HStack(spacing: 10.0) {
Image(systemName: "person.fill")
.resizable()
.scaledToFit()
.frame(width: 20.0, height: 20.0)
Text("This is a 1st row.")
}
.scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
.scrollViewRowSeparatorInsets(EdgeInsets(top: 0.0, leading: 70.0, bottom: 0.0, trailing: 0.0))
Text("This is a 2nd row.")
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
.scrollViewSectionStyle(.insetGrouped)
}
}
.scrollViewSectionStyle(.grouped)
.scrollViewSectionBackgroundColor(.clear)
.background {
Color(uiColor: UIColor.systemGroupedBackground)
.ignoresSafeArea()
}
}
}
It should look like this ⬇️
Row – Context Menu
You can also add a context menu for the row by applying the modifier. This modifier can be used per section or per row.scrollViewRowContextMenu(@ViewBuilder _ menuItems: @escaping () -> some View)
In the following example the second row of the first section uses multiple buttons with the component between them.Divider
import ScrollViewSectionKit
struct ContentView: View {
var body: some View {
ScrollView {
VStack(spacing: 0.0) {
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
.scrollViewRowContextMenu {
Button {
} label: {
Label("Star", systemImage: "star")
}
Button {
} label: {
Label("Profile", systemImage: "person")
}
Divider()
Button(role: .destructive) {
} label: {
Label("Block", systemImage: "hand.raised")
}
}
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
ScrollViewSection {
Text("This is a 1st row.")
Text("This is a 2nd row.")
} header: {
Text("Section header".uppercased())
} footer: {
Text("Section footer")
}
.scrollViewSectionStyle(.insetGrouped)
}
}
.scrollViewSectionStyle(.grouped)
.scrollViewSectionBackgroundColor(.clear)
.background {
Color(uiColor: UIColor.systemGroupedBackground)
.ignoresSafeArea()
}
}
}
