2. run a new container from image
3. press down-arrow / click down on "Host port" nav key down

Expected behavior

hi, thanks for reporting this.

Upon checking, we noticed that your Docker Desktop version (4.16.2) is not updated to date.

Please try the latest version (4.30.0) and see if you are still experiencing the same issue. https://docs.docker.com/desktop/release-notes/#4300

@voonyee thank you for your response After updating to latest (4.30.0) The "arrow down" was solved, and I can't go lower from 0- But it could still occur when inserting a dash (-) into the port field (i.e. -5)

I'm not sure if it's on purpose - but there's a limit of 2 dashes (i.e. --)

Docker responded with 400

I propose that the filed input should be positive integer only

this also occurs : the argument --e (which I think is also on purpose)

It allows the container to be built after hitting "Run"
