+import AutoScreenshot from "@components/AutoScreenshot.astro"
+
+## Overview
+
+The select column allows you to render a select field inside the table, which can be used to update that database record without needing to open a new page or a modal.
+
+You must pass options to the column:
+
+```php
+use Filament\Tables\Columns\SelectColumn;
+
+SelectColumn::make('status')
+    ->options([
+        'draft' => 'Draft',
+        'reviewing' => 'Reviewing',
+        'published' => 'Published',
+    ])
+```
+
+<AutoScreenshot name="tables/columns/select/simple" alt="Select column" version="3.x" />
+
+## Validation
+
+You can validate the input by passing any [Laravel validation rules](https://laravel.com/docs/validation#available-validation-rules) in an array:
+
+```php
+use Filament\Tables\Columns\SelectColumn;
+
+SelectColumn::make('status')
+    ->options([
+        'draft' => 'Draft',
+        'reviewing' => 'Reviewing',
+        'published' => 'Published',
+    ])
+    ->rules(['required'])
+```
+
+## Disabling placeholder selection
+
+You can prevent the placeholder from being selected using the `selectablePlaceholder()` method:
+
+```php
+use Filament\Tables\Columns\SelectColumn;
+
+SelectColumn::make('status')
+    ->options([
+        'draft' => 'Draft',
+        'reviewing' => 'Reviewing',
+        'published' => 'Published',
+    ])
+    ->selectablePlaceholder(false)
+```
+
+## Lifecycle hooks
+
+Hooks may be used to execute code at various points within the select's lifecycle:
+
+```php
+SelectColumn::make()
+    ->beforeStateUpdated(function ($record, $state) {
+        // Runs before the state is saved to the database.
+    })
+    ->afterStateUpdated(function ($record, $state) {
+        // Runs after the state is saved to the database.
+    })
+```
