// # Panel - Filter variant

// Implements the [Panel design pattern](https://www.lightningdesignsystem.com/components/panels) in React.
// Based on SLDS v2.2.0-rc.1

// ## Dependencies

// ### React
import React from 'react';
import PropTypes from 'prop-types';

// ### classNames
import classNames from 'classnames';

// This component's `checkProps` which issues warnings to developers about properties when in development mode (similar to React's built in development tools)
import checkProps from './check-props';
import componentDoc from './docs.json';

// ## Constants
import { PANEL } from '../../utilities/constants';

 * A panel provides detailed contextual information or contextual filtering options. [Filter](/components/filters/) component should be used as children. Menus within a Filter Popover will need to not have "portal mounts" and be inline. */
