The content of a drop down (<select>) is not visible

[tby333]

Hey everybody :)
I have the following problem:

What steps will reproduce the problem?

1. Go to https://www.w3schools.com/TAGS/tryit.asp?filename=tryhtml_select
2. Click on the drop down list

What is the expected output? What do you see instead?

• The expected output is to see the content of the dropdown field

• Instead the dropdown content is not visible, but i can click on the
  position where the content should be...

• If you go to https://www.w3schools.com/TAGS/tag_select.asp and click on "Try it Yourself",
  there will be opened the above site in a new window.
  -> the drop down does work?

What version of the product are you using? On what operating system?

• cef3 3.2883.1553
• Windows 10
• Firemonkey

I hope someone can help me to handle this :)

Once I had the problem, that the drop down list was at the wrong position after moving the form.
I fixed it by adding this lines of code.

type
TForm1 = class(TForm)
[...]
Chromium: TChromium;
procedure OnMove(var Msg: TWMMove); message WM_MOVE;
[...]
end;

implementation

procedure TForm1.OnMove(var Msg: TWMMove);
begin
inherited;
if Assigned(Chromium.Browser) then begin
try
Chromium.Browser.Host.NotifyMoveOrResizeStarted;
finally
end;
end;
end;

I hope this helps to fix your problem :)

Hey TimmyTommy,
i forgot to mention that i use it for firemonkey. I think your solution works fine for the VCL version, but unfortunately not for me.
But still thank you for your fast reply :)
Maybe somebody else can help me?
