可以通过在AG Grid上注册通用菜单选项卡回调函数来自定义该菜单。但是，如果在企业版中进行自定义，您可能会遇到回调函数没有被调用的情况。这可能是由于选项卡本身已经被定制化导致的。

为了解决此问题，您需要将您的回调函数附加到“menuItemComponent”的“afterGuiAttached”时期。代码示例如下：

import { AllCommunityModules } from '@ag-grid-community/all-modules';

const menuItemComponent = (params) => {
  const eMenu = document.createElement('div');
  const template = `
    
Do Something Special
  `;
  eMenu.innerHTML = template;
  const onClickHandler = () => {
    params.api.deselectAll();
    params.api.refreshCells({force: true});
  };
  eMenu.addEventListener('click', onClickHandler);
  params.onClose = () => {
    eMenu.removeEventListener('click', onClickHandler);
  };
  params.showMenu(eMenu);
};

const columnDefs = [
  { field: 'make' },
  { field: 'model' },
  { field: 'price' }
];

const gridOptions = {
  rowSelection: 'multiple',
  columnDefs: columnDefs,
  animateRows: true,
  modules: AllCommunityModules,
  getMainMenuItems: (params) => {
    const originalMenuItems = params.defaultItems;
    const customMenuItems = [
      {
        name: 'customItem',
        action: function () {
          console.log('customItem clicked');
        },
        cssClasses: ['fa fa-bomb'],
        tooltip: 'Custom Item'
      }
    ];
    return customMenuItems.concat(originalMenuItems);
  },
  components: {
    menuItemComponent
  },
  processRowPostCreate: (params) => {
    params.eRow.addEventListener('contextmenu', (event) => {
      event.preventDefault();
      event.stopPropagation();
      setTimeout(() => {
        params.api.showPopupMenu(params.column.getColId(), event);
      }, 0);
    });
  }
};

const gridDiv = document.querySelector('#myGrid');

new agGrid.Grid(gridDiv, gridOptions);

agGrid.simpleHttpRequest({ url: 'https://api.myjson.com/bins/15psn9' })
  .then(function (data) {
    gridOptions.api.setRowData(data);
  });

在这个示例中，我们向AG Grid添加了我们的菜单项目，并注册了我们的menuItemComponent回调函数。这个例子允许您
