+## Overview
+
+A **selection input** is a form control that allows users to choose one option from a predefined list of options.
+
+The selected option is typically displayed in a single-line text field, with the list of options hidden until the user interacts with the control.
+
+## Use Cases
+
+### When to use:
+
+- When users need to select a single option from a list of predefined choices
+- When the list of options is relatively short (less than 10-15 items)
+- When screen space is limited, and displaying all options at once is not feasible
+- When the selected option doesn't need to be visible at all times
+
+### When not to use:
+
+- When users need to select multiple options (use checkboxes or a [multi-select](/patterns/forms/multi-select-input) instead)
+- When the list of options is very long (consider using an [autocomplete](/patterns/forms/autocomplete) or a typeahead)
+- When users need to input free-form text (use a regular text input instead)
+- When the options are complex or require additional information or visual aids
+
+### Common scenarios and examples
+
+- Selecting a country from a list of all countries
+- Choosing a preferred language from a list of supported languages
+- Selecting a payment method during checkout
+- Choosing a size, color, or other product variant on an e-commerce site
+
+## Benefits
+
+- Saves screen space by hiding options until needed
+- Provides a clear and concise way to select from predefined options
+- Prevents user input errors by limiting choices to valid options
+- Allows for easy selection using a mouse, keyboard, or touch input
+
+## Anatomy
+
+### Component Structure
+
+```mermaid
+graph TD
+    A[Selection Input Container] --> B[Text Field]
+    A --> C[Dropdown List]
+    B --> B1[Selected Value]
+    B --> B2[Caret Icon]
+    C --> D1[Option 1]
+    C --> D2[Option 2]
+    C --> D3[Option 3]
+    C --> E[Scrollbar]
+```
+
+1. **Container**
+
+   - Wraps the selection input and its associated elements
+   - Defines the overall dimensions and positioning of the component
+
+2. **Text Field**
+
+   - Displays the currently selected option
+   - Acts as a button to trigger the dropdown list
+   - Often includes a caret or arrow icon to indicate the presence of a dropdown
+
+3. **Dropdown List**
+
+   - Contains the list of available options
+   - Appears when the text field is clicked or receives focus
+   - Can be positioned above or below the text field, depending on available space
+
+4. **Options**
+
+   - Individual items within the dropdown list
+   - Represent the available choices for the user
+   - Should have a clear and concise label
+   - Can include icons, images, or other visual aids if necessary
+
+5. **Scrollbar (Optional)**
+
+   - Allows users to scroll through the list of options if the list is too long to fit within the available space
+   - Can be styled to match the overall design of the component
+
+## Best Practices
+
+### Content
+
+**Do's ✅**
+
+- Use clear and concise labels for each option
+- Keep the list of options relatively short (less than 10-15 items)
+- Order options logically (e.g., alphabetically, by popularity, or by relevance)
+- Provide a default or pre-selected option when applicable
+
+**Don'ts ❌**
+
+- Don't use overly long or complex option labels
+- Avoid using jargon or technical terms that users may not understand
+- Don't include options that are not relevant or applicable to the user's context
+
+### Accessibility & UX
+
+**Do's ✅**
+
+- Ensure the selection input is keyboard accessible (arrow keys to navigate, Enter to select)
+- Provide a clear focus state for the text field and individual options
+- Use ARIA attributes to communicate the component's state and purpose
+- Allow users to filter or search the list of options if the list is long
+
+**Don'ts ❌**
+
+- Don't rely solely on color to convey the state or purpose of the component
+- Avoid using auto-selection or auto-submission when an option is highlighted
+- Don't change the order or content of options unexpectedly
+
+### Visual Design
+
+**Do's ✅**
+
+- Use a consistent visual style for the text field, dropdown list, and options
+- Provide ample whitespace and padding to improve readability and usability
+- Use a contrasting color or style to indicate the selected option
+- Ensure the dropdown list is visually distinct from the text field
+
+**Don'ts ❌**
+
+- Don't use low-contrast colors or small font sizes that reduce legibility
+- Avoid using overly complex or decorative styles that distract from the content
+- Don't make the dropdown list too narrow or too wide relative to the text field
+
+### Layout & Positioning
+
+**Do's ✅**
+
+- Position the dropdown list close to the text field for easy association
+- Ensure the dropdown list doesn't obstruct other important content or UI elements
+- Align the text field and dropdown list with other form controls for a cohesive layout
+
+**Don'ts ❌**
+
+- Don't place the dropdown list too far away from the text field
+- Avoid positioning the dropdown list in a way that requires excessive scrolling or mouse movement
+
+## Code Examples
+
+### Basic Implementation
+
+```html
+<label for="fruits">Choose a fruit:</label>
+<select id="fruits" name="fruits">
+  <option value="apple">Apple</option>
+  <option value="banana">Banana</option>
+  <option value="orange">Orange</option>
+  <option value="strawberry">Strawberry</option>
+</select>
+```
+
+## Browser Support

+    "html.elements.select",
+    "html.elements.option",
+    "html.elements.optgroup",
