# Layout Customization

## Overview

The Layout Customization feature allows developers to adjust how controls are arranged within the SiticoneFlowPanel. This includes configuring spacing between items, enabling or disabling wrapping, caching layout states for performance improvements, snapping items to a grid, and providing methods to automatically arrange or size the panel based on its contents. Properties such as `ItemSpacing`, `EnableWrapping`, `EnableLayoutCaching`, `EnableSnapToGrid`, and `GridSize` play a central role in managing these behaviors, while the `RefreshLayout()` method and extension methods like `ArrangeInGrid(int columns)` and `AutoSizeToContents()` offer additional control over layout dynamics.

#### 3. Code Examples

**Example 1: Basic Layout Customization**

This example demonstrates how to configure the layout properties of the SiticoneFlowPanel to create a well-organized interface.

```csharp
using System;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

namespace LayoutDemo
{
    public partial class MainForm : Form
    {
        private SiticoneFlowPanel flowPanel;

        public MainForm()
        {
            InitializeComponent();
            InitializeFlowPanel();
        }

        private void InitializeFlowPanel()
        {
            flowPanel = new SiticoneFlowPanel
            {
                Dock = DockStyle.Fill,
                ItemSpacing = 10,             // Set spacing between controls
                EnableWrapping = true,        // Allow controls to wrap to the next line
                EnableLayoutCaching = true,   // Enable caching for improved layout performance
                EnableSnapToGrid = true,      // Enable snap-to-grid for precise alignment
                GridSize = 10                 // Set grid size for snap-to-grid functionality
            };

            // Add sample controls
            for (int i = 1; i <= 6; i++)
            {
                Button button = new Button
                {
                    Text = $"Button {i}",
                    Width = 100,
                    Height = 30
                };
                flowPanel.Controls.Add(button);
            }

            Controls.Add(flowPanel);
        }
    }
}
```

**Example 2: Using Extension Methods for Dynamic Layouts**

The following example uses extension methods to arrange controls in a grid and to auto-size the panel based on its contents.

```csharp
using System;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;
using SiticoneNetFrameworkUI.AdvancedFlowPanelExtensions; // Assuming extensions are in this namespace

namespace LayoutDemo
{
    public partial class MainForm : Form
    {
        private SiticoneFlowPanel flowPanel;

        public MainForm()
        {
            InitializeComponent();
            InitializeFlowPanel();
            DemoExtensions();
        }

        private void InitializeFlowPanel()
        {
            flowPanel = new SiticoneFlowPanel
            {
                Dock = DockStyle.Fill,
                ItemSpacing = 8,
                EnableWrapping = true,
                EnableLayoutCaching = true,
                EnableSnapToGrid = true,
                GridSize = 8
            };

            // Add sample controls
            for (int i = 1; i <= 8; i++)
            {
                Label label = new Label
                {
                    Text = $"Label {i}",
                    Width = 80,
                    Height = 25,
                    BorderStyle = BorderStyle.FixedSingle
                };
                flowPanel.Controls.Add(label);
            }

            Controls.Add(flowPanel);
        }

        private void DemoExtensions()
        {
            // Arrange the controls into 4 columns using the extension method
            flowPanel.ArrangeInGrid(4);

            // Automatically resize the panel to fit its contents
            flowPanel.AutoSizeToContents();
        }
    }
}
```
