 * @class DropdownMenu
 * @plugin DropdownMenu
 *
 * @description
 * This plugin creates the Handsontable Dropdown Menu. It allows to create a new row or column at any place in the grid
 * among [other features](https://handsontable.com/docs/demo-context-menu.html).
 * Possible values:
 * * `true` (to enable default options),
 * * `false` (to disable completely).
 *
 * or array of any available strings:
 * * `["row_above", "row_below", "col_left", "col_right",
 * "remove_row", "remove_col", "---------", "undo", "redo"]`.
 *
 * See [the dropdown menu demo](https://handsontable.com/docs/demo-dropdown-menu.html) for examples.
 *
 * @example
 * ```
 * const container = document.getElementById('example');
 * const hot = new Handsontable(container, {
 *   data: data,
 *   colHeaders: true,
 *   // enable dropdown menu
 *   dropdownMenu: true
 * });
 *
 * // or
 * const hot = new Handsontable(container, {
 *   data: data,
 *   colHeaders: true,
 *   // enable and configure dropdown menu
 *   dropdownMenu: ['remove_col', '---------', 'make_read_only', 'alignment']
 * });
 * ```
