+import AutoScreenshot from "@components/AutoScreenshot.astro"
+
+## Overview
+
+You may group actions together into a dropdown menu by using an `ActionGroup` object. Groups may contain many actions, or other groups:
+
+```php
+ActionGroup::make([
+    Action::make('view'),
+    Action::make('edit'),
+    Action::make('delete'),
+])
+```
+
+<AutoScreenshot name="actions/group/simple" alt="Action group" version="3.x" />
+
+This page is about customizing the look of the group's trigger button and dropdown.
+
+## Customizing the group trigger style
+
+The button which opens the dropdown may be customized in the same way as a normal action. [All the methods available for trigger buttons](trigger-button) may be used to customize the group trigger button:
+
+```php
+use Filament\Support\Enums\ActionSize;
+
+ActionGroup::make([
+    // Array of actions
+])
+    ->label('More actions')
+    ->icon('heroicon-m-ellipsis-vertical')
+    ->size(ActionSize::Small)
+    ->color('primary')
+    ->button()
+```
+
+<AutoScreenshot name="actions/group/customized" alt="Action group with custom trigger style" version="3.x" />
+
+## Setting the placement of the dropdown
+
+The dropdown may be positioned relative to the trigger button by using the `dropdownPlacement()` method:
+
+```php
+ActionGroup::make([
+    // Array of actions
+])
+    ->dropdownPlacement('top-start')
+```
+
+<AutoScreenshot name="actions/group/placement" alt="Action group with top placement style" version="3.x" />
+
+## Adding dividers between actions
+
+You may add dividers between groups of actions by using nested `ActionGroup` objects:
+
+```php
+ActionGroup::make([
+    ActionGroup::make([
+        // Array of actions
+    ])->dropdown(false),
+    // Array of actions
+])
+```
+
+The `dropdown(false)` method puts the actions inside the parent dropdown, instead of a new nested dropdown.
+
+<AutoScreenshot name="actions/group/nested" alt="Action groups nested with dividers" version="3.x" />
+
+## Setting the width of the dropdown
+
+The dropdown may be set to a width by using the `dropdownWidth()` method. Options correspond to [Tailwind's max-width scale](https://tailwindcss.com/docs/max-width). The options are `ExtraSmall`, `Small`, `Medium`, `Large`, `ExtraLarge`, `TwoExtraLarge`, `ThreeExtraLarge`, `FourExtraLarge`, `FiveExtraLarge`, `SixExtraLarge` and `SevenExtraLarge`:
+
+```php
+use Filament\Support\Enums\MaxWidth;
+
+ActionGroup::make([
+    // Array of actions
+])
+    ->dropdownWidth(MaxWidth::ExtraSmall)
+```
+
+## Controlling the maximum height of the dropdown
+
+The dropdown content can have a maximum height using the `maxHeight()` method, so that it scrolls. You can pass a [CSS length](https://developer.mozilla.org/en-US/docs/Web/CSS/length):
+
+```php
+ActionGroup::make([
+    // Array of actions
+])
+    ->maxHeight('400px')
+```
+
+## Controlling the dropdown offset
+
+You may control the offset of the dropdown using the `dropdownOffset()` method, by default the offset is set to `8`.
+
+```php
+ActionGroup::make([
+    // Array of actions
+])
+    ->dropdownOffset(16)
+```
