i have a multiple lookup field.
How can i by clicking checkbox "select all" - to select all values in lookup field?
You could add a button with pnpjs code to retrieve all items, then create an array with all item IDs and populate the Lookup field with it.

i tried as is in manual, but have some problems - values are populated but undefined
Cod in button:
fd.field('Sucursale_x0020_adresate').value=["400","401","402"]; console.log(fd.field('Sucursale_x0020_adresate').value); console.log(fd.field('Sucursale_x0020_adresate').value.Cod_x0020_Subdiviziune);
Yes, the extra values are not available if you set the value with code. You can only retrieve these with pnpjs, as shown in the links above.
