Answer 1

you need to use the placeholderLabel attribute (see https://github.com/bithost-gmbh/ngx-mat-select-search#inputs)

<ngx-mat-select-search 
formControlName="vehicleMakerFilterInputValue" 
placeholderLabel="Select Motor Maker" 
[noEntriesFoundLabel]="'No matching vehicle makers found'" 
(ngModelChange)='filter_vehicle_makers($event)' 
i18n-placeholderLabel>
</ngx-mat-select-search>

where the placeholderLabel and i18n-placeholderLabel attributes are relevant
