# Close Button Styling & Layout

## Overview

The Close Button Styling & Layout feature provides extensive customization options for the close button that appears on the chip control. This feature allows you to control the button’s visibility, icon appearance, size, padding, and border details, as well as its behavior when hovered over. With these properties, developers can integrate a close functionality that aligns with the application's design language and user experience requirements.

### Best Practices

| Practice                                    | Explanation                                                                                                                                            |
| ------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Maintain consistent spacing                 | Ensure that the padding values (both outer and inner) are consistent with other UI elements to maintain visual harmony.                                |
| Use appropriate contrast for hover elements | Choose hover colors (for icon, border, and background) that provide sufficient contrast with the default state to clearly indicate interactivity.      |
| Test various sizes and thicknesses          | Adjust the close button size and icon thickness according to the overall control size to prevent the button from appearing too dominant or too subtle. |
| Consider user accessibility                 | Ensure that the close button is easily clickable and visually clear even for users with visual impairments.                                            |

#### Code Example: Customizing the Close Button Appearance

```csharp
// Create a chip with a customized close button
var chipWithClose = new SiticoneGroupChip
{
    Text = "Closable Chip",
    // Enable the close button
    ShowCloseButton = true,
    
    // Customize icon appearance
    CloseIconColor = Color.DarkGray,
    CloseIconHoverColor = Color.Red,
    CloseIconThickness = 2.0f,
    CloseIconSize = 24,
    
    // Adjust layout and padding
    CloseIconPadding = new Padding(6),
    CloseIconInnerPadding = 3,
    
    // Customize border and hover background for the close button
    ShowCloseButtonBorder = true,
    CloseButtonBorderColor = Color.LightGray,
    CloseButtonBorderThickness = 1f,
    CloseButtonHoverBackColor = Color.FromArgb(50, Color.Gray)
};

// Add the chip to a container (e.g., a Form or Panel)
this.Controls.Add(chipWithClose);
```

### Common Pitfalls

<table><thead><tr><th width="325">Pitfall</th><th>Explanation</th></tr></thead><tbody><tr><td>Inadequate padding adjustments</td><td>Failing to adjust the padding may lead to the close button overlapping with the text or other elements. Always ensure that the chip's padding is recalculated when enabling the close button.</td></tr><tr><td>Mismatched size and thickness</td><td>Setting the close icon size or thickness outside reasonable bounds can result in an icon that appears too small or too large relative to the chip. Use provided range limits (e.g., a minimum of 12 pixels and maximum of 32 pixels for size).</td></tr><tr><td>Overcomplicating hover styling</td><td>Using overly complex hover styles (excessively bright colors or thick borders) may distract users from the primary content of the chip.</td></tr><tr><td>Ignoring user interaction feedback</td><td>Not testing the hover states and click areas can lead to a close button that feels unresponsive or hard to interact with.</td></tr></tbody></table>

#### Code Example: Avoiding Layout Pitfalls

```csharp
// Ensure proper layout when the close button is enabled
var chipLayoutSafe = new SiticoneGroupChip
{
    Text = "Safe Layout Chip",
    ShowCloseButton = true,
    
    // Use moderate sizes and padding values
    CloseIconSize = 20,                   // Within the acceptable range (12 - 32)
    CloseIconThickness = 1.5f,
    CloseIconPadding = new Padding(8),
    CloseIconInnerPadding = 4,
    
    // Set subtle hover styling for better UX
    CloseIconColor = Color.Black,
    CloseIconHoverColor = Color.FromArgb(255, 64, 64, 64),
    ShowCloseButtonBorder = false
};

this.Controls.Add(chipLayoutSafe);
```

### Usage Scenarios

<table><thead><tr><th width="311">Scenario</th><th>Description</th></tr></thead><tbody><tr><td>Removable Tag or Label</td><td>Use chips with close buttons in tagging systems where users can remove tags or labels by clicking the close icon.</td></tr><tr><td>Dismissible Notifications or Alerts</td><td>Implement chips as part of a notification system where each chip can be dismissed by the user using the close button.</td></tr><tr><td>Dynamic List Management</td><td>Use the close button to allow users to remove items from a list or filter out certain options in a dynamic user interface.</td></tr></tbody></table>

#### Code Example: Dismissible Notification Chip

```csharp
// Create a chip used as a dismissible notification
var notificationChip = new SiticoneGroupChip
{
    Text = "You have 3 new messages",
    ShowCloseButton = true,
    CloseIconColor = Color.DarkSlateGray,
    CloseIconHoverColor = Color.Red,
    CloseIconSize = 22,
    CloseIconThickness = 2.0f,
    CloseIconPadding = new Padding(5),
    CloseIconInnerPadding = 3,
    ShowCloseButtonBorder = true,
    CloseButtonBorderColor = Color.Gray,
    CloseButtonBorderThickness = 1f,
    CloseButtonHoverBackColor = Color.FromArgb(40, Color.Gray)
};

// Optionally, subscribe to the CloseClicked event to perform an action when the chip is dismissed.
notificationChip.CloseClicked += (sender, e) =>
{
    // Custom logic on chip close; for example, remove the chip from its parent container.
    notificationChip.Parent.Controls.Remove(notificationChip);
    notificationChip.Dispose();
};

this.Controls.Add(notificationChip);
```

### Real Life Usage Scenarios

<table><thead><tr><th width="286">Real Life Scenario</th><th>Example</th></tr></thead><tbody><tr><td>Email Client Interface</td><td>In an email client, each email preview chip may have a close button to quickly dismiss or archive unwanted messages.</td></tr><tr><td>E-commerce Filter Selection</td><td>Use chips with close buttons to allow users to remove applied filters on a product search page, enhancing the browsing experience.</td></tr><tr><td>Social Media Tag Management</td><td>In social media platforms, users can remove tags or keywords by clicking on the close button on each chip representing a tag.</td></tr></tbody></table>

#### Code Example: E-commerce Filter Chip

```csharp
// Create a chip for an e-commerce filter that can be removed by the user
var filterChip = new SiticoneGroupChip
{
    Text = "Price: Under $50",
    ShowCloseButton = true,
    CloseIconColor = Color.Black,
    CloseIconHoverColor = Color.Orange,
    CloseIconSize = 20,
    CloseIconThickness = 1.5f,
    CloseIconPadding = new Padding(8),
    CloseIconInnerPadding = 4,
    ShowCloseButtonBorder = false
};

// Remove the filter when the close button is clicked
filterChip.CloseClicked += (sender, e) =>
{
    // Remove the filter chip from the panel and update the product list accordingly.
    filterChip.Parent.Controls.Remove(filterChip);
    filterChip.Dispose();
};

filterPanel.Controls.Add(filterChip);
```
