The Header Menu is now part of Slickgrid-Universal 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-Universal is configured by default with these settings (you can overwrite any one of them):
this.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
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.
You can disable the Header Menu, by calling enableHeaderMenu: false from the Grid Options.
this.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:
