+
+## Overview
+
+You may want to group fields into a Fieldset. Each fieldset has a label, a border, and a two-column grid by default:
+
+```php
+use Filament\Forms\Components\Fieldset;
+
+Fieldset::make('Label')
+    ->schema([
+        // ...
+    ])
+```
+
+<AutoScreenshot name="forms/layout/fieldset/simple" alt="Fieldset" version="3.x" />
+
+## Using grid columns within a fieldset
+
+You may use the `columns()` method to customize the [grid](grid) within the fieldset:
+
+```php
+use Filament\Forms\Components\Fieldset;
+
+Fieldset::make('Label')
+    ->schema([
+        // ...
+    ])
+    ->columns(3)
+```
