Is this going to make it into a future milestone?

Bump! - It's very intuitive to start typing in classic "select" elements to find desired value so it would be very appreciated to have this feature also in Prime's dropdown :)

Current partial workaround is to enable "filtering", but it's a little bit annoying for the user (more clicks).

I would also love this to be included as a standard feature of the dropdown. For form input, especially repeated input, many users are used to tabbing through the form and typing, not having to reach over for the mouse for every dropdown. Without this feature the normal and expected behavior for a dropdown is missing.

Almost one year and nothing has been done?
It's really the minimum requirement for a dropdown.

@mlaffargue

<p-dropdown [options]="items" (keyup)="onKeyUp($event)" filter="true"></p-dropdown>

onKeyUp(event) {
    console.log(event.target.value);
}

OR

<p-dropdown [options]="items" (keyup.enter)="onKeyUp($event)" filter="true"></p-dropdown>

This issue happen again in the version 7.0.5

I think the root cause is in file primeng/src/app/components/dropdown/dropdown.ts, line 54,

<input #filter type="text" autocomplete="off" [value]="filterValue||''" class="ui-dropdown-filter ui-inputtext ui-widget ui-state-default ui-corner-all" [attr.placeholder]="filterPlaceholder" (keydown.enter)="$event.preventDefault()" (keydown)="onKeydown($event, false)" (input)="onFilter($event)" [attr.aria-label]="ariaFilterLabel">

we have addition code: (input)="onFilter($event)", and this bug is happen again.
