IColumnDefinition

Minimal column info used by the column chooser:

interface IColumnDefinition {
  columnId: string;
  name: string;
  required?: boolean;
}

Field	Type	Description
columnId	string	Unique column identifier.

Usage

Basic Example (React)

import { ColumnChooser } from '@alaarab/ogrid-react-radix';
import type { IColumnDefinition } from '@alaarab/ogrid-react-radix';

function MyApp() {
  const columns: IColumnDefinition[] = [
    { columnId: 'id', name: 'ID', required: true },
    { columnId: 'name', name: 'Product Name' },
    { columnId: 'price', name: 'Price' },
    { columnId: 'category', name: 'Category' },
  ];

  const [visibleColumns, setVisibleColumns] = useState<Set<string>>(
    new Set(['id', 'name', 'price'])
  );

  const handleVisibilityChange = (columnKey: string, visible: boolean) => {
    const newSet = new Set(visibleColumns);
    if (visible) {
      newSet.add(columnKey);
    } else {
      newSet.delete(columnKey);
    }
    setVisibleColumns(newSet);
  };

  return (
    <ColumnChooser
      columns={columns}
      visibleColumns={visibleColumns}
      onVisibilityChange={handleVisibilityChange}
    />
  );
}

With Required Columns (React)

import { ColumnChooser } from '@alaarab/ogrid-react-radix';

const columns: IColumnDefinition[] = [
  { columnId: 'id', name: 'ID', required: true }, // Cannot be hidden
  { columnId: 'name', name: 'Product Name', required: true }, // Cannot be hidden
  { columnId: 'price', name: 'Price' },
  { columnId: 'stock', name: 'Stock' },
];

function MyApp() {
  // ... (same as above)
  return (
    <ColumnChooser
      columns={columns}
      visibleColumns={visibleColumns}
      onVisibilityChange={handleVisibilityChange}
    />
  );
}

The "ID" and "Product Name" columns will have disabled checkboxes and cannot be hidden.

Behavior

Select All / Clear All

The dropdown includes two action buttons:

• Select All - Shows all columns (except those marked as required: false - these remain hidden)
• Clear All - Hides all optional columns (required columns remain visible)

Visual Indicator

The trigger button shows the current visibility count: "Column Visibility (3 of 5)".

Checkbox States

• Checked - Column is visible
• Unchecked - Column is hidden
• Disabled + Checked - Column is required and cannot be hidden

Accessibility

ColumnChooser implements WCAG 2.1 AA standards with full keyboard and screen reader support.

ARIA Attributes

<button aria-expanded="false" aria-haspopup="listbox">
  Column Visibility (3 of 5)
</button>
<div role="dialog" aria-label="Column visibility">
  <input type="checkbox" id="col-name" />
  <label for="col-name">Product Name</label>
</div>

Attribute	Element	Purpose
aria-expanded	Trigger button	Indicates dropdown open/closed state ("true" / "false")
aria-haspopup="listbox"	Trigger button	Indicates the button triggers a listbox
role="dialog"	Dropdown	Identifies the dropdown as a modal dialog
aria-label="Column visibility"	Dropdown	Provides context for the dialog
id / for	Checkbox + label	Associates each checkbox with its label
disabled	Checkbox	Indicates required columns that cannot be hidden

Keyboard Navigation

• Enter / Space (on trigger button) - Open/close dropdown
• Tab / Shift+Tab - Navigate between checkboxes and action buttons
• Space - Toggle focused checkbox
• Enter (on action buttons) - Execute "Select All" or "Clear All"
• Escape - Close dropdown

Focus Management

• Focus trap: Focus is trapped within the dropdown when open
• Focus restoration: When closing the dropdown, focus returns to the trigger button
• Focus visible: :focus-visible styles show 2px solid outline (--ogrid-accent)

Screen Reader Support

Screen readers announce:

• Trigger button: "Column Visibility (3 of 5) button, collapsed/expanded"
• Checkbox state: "Product Name checkbox, checked/unchecked"
• Required columns: "ID checkbox, checked, disabled, required column"
• Action buttons: "Select All button", "Clear All button"

Tested with NVDA, JAWS, VoiceOver, and Narrator.

High Contrast Mode

• Checkboxes remain visible in high contrast mode
• Focus indicators use system Highlight color
• Dropdown borders use system ButtonText color

See the Accessibility Guide for complete documentation.

Styling

All UI packages provide default styles matching their design system. Styles are scoped to avoid conflicts.

CSS custom properties (all packages):

• --ogrid-header-bg - Trigger button and popover background color
• --ogrid-border - Border color
• --ogrid-fg - Foreground text color

Placement in OGrid

The columnChooser prop on OGrid controls where the column chooser renders:

• true or 'toolbar' (default) - Renders in the toolbar strip (recommended)
• 'sidebar' - Only available via the sidebar columns panel (no toolbar button)
• false - Hidden entirely (useful when you want full control over visibility)

Related Components

• DataGridTable - Main grid component
• SideBar - Sidebar with columns panel (alternative placement)
• OGrid - Top-level wrapper that integrates the column chooser
