Standard HTML combobox (see [1]: SELECT and DATALIST) works without problems so in your case there's something else going on.
You'll need to provide the URL exhibiting the problem or mock up a demo on jsfiddle.net
Are there any relevant error messages in devtools console?

Can we have a hangout/webex to show the issue? It's very critical, This is issue with HPSM Enterprise application which is very critcal.

Waiting for a Chromium developer who can connect to your computer might take too long.
I think it's better for you to ask your developers to use https://www.chromium.org/developers/bisect-builds-py
That script downloads and runs pre-built Chromium snapshots and in the end prints a long changelog link that contains the change that's causing the bug.

...use https://omahaproxy.appspot.com to obtain revision numbers e.g. for v61 - v62 range:
python bisect-builds.py -a win64 -g 488528 -b 499098 -- http://your.app.url/

//Below element on 62.0.3202.75 (Official Build) (64-bit). which is unexpected....as it should be hidden...which is creating issue.

Unable to reproduce this issue on Windows-7 & 10 using chrome latest stable #62.0.3202.75 using the below test link http://docs.sencha.com/extjs/4.2.5/extjs-build/examples/form/combos.html. Observed able to see all the items in the list box and able to select the value as expected. Tested the same on some internal applications as well, still unable to reproduce the issue.

malle.reddy@ Could you please provide any sample test case or test URL of your application to check this issue from Chrome-TE end? As per comment #4 and #5 are you able to perform bisect from your end?

Thanks!

 

Thank you for the update...

You can run the jsfiddle against two, When ran seperately, snippet2 works, but with the total html, it's broken, it used to work before. Please FIX ASAP...

Thank you for providing more feedback. Adding requester "brajkumar@chromium.org" to the cc list and removing "Needs-Feedback" label.

While opening the first test case file from comment #17 observed the page is completely broken and while opening the second test case file from comment #18 page loads perfectly. In the both the test cases am not seeing any combo boxes available to check the issue, observing similar behavior on Firefox browser as well.

Not sure if this is a complete test case file where we can reproduce the actual issue, could you please provide a working test case to check this issue from Chrome-TE end? 

Thanks!



 

After having an offline discussion with the reporter confirming this issue still persists on chrome latest stable M62. Observing some random mandatory drop down box in the page, and these drop down boxes doesn’t have any values to select.

Due to this issue reporter is unable to submit any orders from their site and it was not seen on previous chrome stable #61.0.3163.100.

Note: 
-----
1. This issue is not reproducible on chrome latest beta M63 #63.0.3239.40. Attaching screen cast for reference.
2. Since this issue is not reproducible from our end, requested reporter to perform bisect using chromium builds and we got the below range as good and bad. 

Bisect Information:
--------------------
Good build: 498335
Bad build:  498560

CL: https://chromium.googlesource.com/chromium/src/+log/afcc763ac1f0cec903036bfc1f61e05c8697bf01..bbf271c3e0989faf73fefd64b26a4625af1287dd

Unable to find the actual suspect from the above CL due to multiple changes are available. Could someone look in to this issue?

Thanks!

M63 stable release is just ~two weeks (12/05) away, so i think we are all set here.

bhanu.chaluvadi@, please feel free to update if you are seeing this issue with Chrome canary (https://www.google.com/chrome/browser/canary.html) Just in case.

Thank you!

Hi,

Will test it after the official go-Live. Thanks for the help :)

Hello Team,

M63 stable release was not deployed on 05/12/2017....Could you please advise us when its going to be released.Thank you.

Regards,
M Linga Reddy

M63 stable should have released public for 2-3 weeks.
Maybe your corp IT is managing the Chrome update, but we cannot be sure.

Reporter, did Chrome 63 fix this issue?

Yes issue is resolved, Support is appreciated..
