javascript - Angular Material - md-autocomplete dropdown's width

Question

I'm using md-autocomplete from Angular Material: here

It seems the dropdown's width goes with the input field's width. If an item's text is too long, there is ellipsis.

However, I want to show full text of an item, while keeping the input field's width relatively short. That is, the dropdown's width should expand with its content.

I tried inspecting the styles of md-autocomplete's elements, but couldn't find any style that does the trick. Any idea?

EDIT:

Here are the style I ended up having:

.md-autocomplete-suggestions-container{
    overflow-y:scroll
}

.md-autocomplete-suggestions-container .md-virtual-repeat-scroller{
    position:static
}

.md-autocomplete-suggestions-container .md-virtual-repeat-sizer{
    height:0 !important
}

.md-autocomplete-suggestions-container .md-virtual-repeat-offsetter{
    position:static
}

However there is one more issue. The overflow-y:scroll always shows the vertial scroll bar even when not needed. If I change it to overflow-y:auto, the vertical scroll bar when present will create ellipsis. How do I solve this?

For anyone still facing the problem of autocomplete values being cropped because the panel width is only as wide as the field, the good news is that it has now been fixed, woohoo!

Angular Material Release 6.4.0 (2018-07-16) introduced the following feature,

• autocomplete: allow panel to have a width value of auto (#11879) (8a5713e)

So now it's possible to just add the property panelWidth with the value auto and the panel will grow to fit the values.

<mat-autocomplete panelWidth="auto">
      <mat-option value="myValue">Now an option with a long label will still be readable<option>
</mat-autocomplete>
