Drop down arrow on mdAutocomplete (like mdSelect h

问题:

Is there a way to get a drop down arrow on md-autocomplete like md-select has?

It provided a visual clue that the control has a drop down, AND allows the user to open the drop down without typing anything

Angular Material does not provide such functionality but you could try to add something like this in your css file:

md-autocomplete-wrap:after {
  display: block;
  content: '\25BC';
  position: relative;
  top: 5px;
  speak: none;
  font-size: 13px;
  left: -10px;
  color: rgba(0,0,0,0.38);
  -webkit-transform: scaleY(.5) scaleX(1);
  transform: scaleY(.5) scaleX(1);
}

Its not perfect solution, but may be enough for you.

And if you want to make dropdown open on click, just add md-min-length="0" attribute to your md-autocomplete.
