Header Menu

The Header Menu is now part of slickgrid-react and is enabled by default via the grid option "enableHeaderMenu" flag.

How to use it?

It's Enabled by default

Technically, it's enable by default and so you don't have anything to do to enjoy it. However if you want to customize the content of the Header Menu, then continue reading.

Customization

Custom Commands

The Header Menu also comes, by default, with a list of built-in custom commands (all their positionOrder are in the reserved range of 40 to 60)

• Sort Ascending (you can hide it with hideSortCommands: true)
• Sort Descending (you can hide it with hideSortCommands: true)
• Hide Column (you can hide it with hideColumnHideCommand: true)

This section is called Custom Commands because you can also customize this section with your own commands. To do that, you need to fill in 2 properties (an array of headerMenuItems that will go under each column definition and define onCommand callbacks) in your Grid Options. For example, slickgrid-react is configured by default with these settings (you can overwrite any one of them):

const gridOptions = {
   enableAutoResize: true,
   enableHeaderMenu: true,   // <<-- this will automatically add extra custom commands
   enableFiltering: true,
   headerMenu: {
     onCommand: (e, args) => {
       if (args.command === 'hide') {
         this.controlService.hideColumn(args.column);
         this.controlService.autoResizeColumns();
       } else if (args.command === 'sort-asc' || args.command === 'sort-desc') {
         // get previously sorted columns
         const cols: ColumnSort[] = this.sortService.getPreviousColumnSorts(args.column.id + '');

         // add to the column array, the column sorted by the header menu
         cols.push({ sortCol: args.column, sortAsc: (args.command === 'sort-asc') });
         this.sortService.onLocalSortChanged(this.gridObj, this.gridOptions, this.dataviewObj, cols);

         // update the this.gridObj sortColumns array which will at the same add the visual sort icon(s) on the UI
         const newSortColumns: ColumnSort[] = cols.map((col) => {
           return { columnId: col.sortCol.id, sortAsc: col.sortAsc };
         });
         this.gridObj.setSortColumns(newSortColumns); // add sort icon in UI
       } else {
         alert('Command: ' + args.command);
       }
     }
  }
};

Callback Hooks

There are 2 callback hooks which are accessible in the Grid Options

• onBeforeMenuShow
• onCommand

For more info on all the available properties of the custom commands, you can read refer to the doc written in the Grid Menu implementation itself.

How to change icon(s) of the default commands?

You can change any of the default command icon(s) by changing the icon[X-command], for example, see below for the defaults.

const gridOptions = {
   enableHeaderMenu: true,
   headerMenu: {
     iconColumnHideCommand: 'fa fa-times'
     iconSortAscCommand: 'fa fa-sort-asc'
     iconSortDescCommand: 'fa fa-sort-desc',
   },
};

How to Disable the Header Menu?

You can disable the Header Menu, by calling enableHeaderMenu: false from the Grid Options.

const gridOptions = {
   enableHeaderMenu: false
};

How to Exclude Header Menu from a Particular Column?

You can exclude a column from getting a Header Menu by calling excludeFromHeaderMenu in your Column Definition. For example, we don't need it on a column that has an edit icon:

const columnDefinitions = [
  { id: 'edit', formatter: Formatters.editIcon, excludeFromHeaderMenu: true, excludeFromExport: true },
  { id: 'title', name: 'Title', field: 'title', sortable: true },
  { id: 'duration', name: 'Duration (days)', field: 'duration', sortable: true },
];

Sample

You can add Header Menu to 1 column or all columns like shown below. You can also add sub-menus by nesting commandItems

// add custom Header Menu to all columns except "Action"
this.columnDefinitions.forEach(col => {
  col.header = {
    menu: {
      commandItems: [
        { command: 'sort-ascending', title: 'Sort Ascending' },
        { command: 'sort-descending', title: 'Sort Descending' },
        'divider',
        {
          // we can also have multiple nested sub-menus
          command: 'custom-actions', title: 'Hello', positionOrder: 99,
          commandItems: [
            { command: 'hello-world', title: 'Hello World' },
            { command: 'hello-slickgrid', title: 'Hello SlickGrid' },
            {
              command: 'sub-menu', title: `Let's play`, cssClass: 'green', subMenuTitle: 'choose your game', subMenuTitleCssClass: 'text-italic salmon',
              commandItems: [
                { command: 'sport-badminton', title: 'Badminton' },
                { command: 'sport-tennis', title: 'Tennis' },
                { command: 'sport-racquetball', title: 'Racquetball' },
                { command: 'sport-squash', title: 'Squash' },
              ]
            }
          ]
        }
      ]
    }
  };
});
