You can easily control the column filtering in ag-Grid by using the getFilterInstance and setModel methods associated to the column you need filtering. Once done, remember to call onFilterChanged to apply your changes.
// a list of all your items you want to filter
// make sure to create a list of strings
// a list of numbers won't work
const listOfItems = data.map((row) => row.ComeColumnItem.toString())
// get the filter instance per column
const filterInstance = this.gridApi?.getFilterInstance('YourColumnName')
// get the existing model in-case you want to modify it
const model = this.gridApi?.getModel()
// or set a new one
filterInstance?.setModel({
type: 'set',
values: listOfItems
})
// remember to apply the changes when done!
this.gridApi?.onFilterChanged()
