Making Details mandatory on popup when Knowledge Article is marked as Not Helpful

[Megan6]

I am trying to make the Details mandatory on the popup when someone marks a Knowledge Article as Not Helpful. I have seen several posts related to this but have not seen quite the solution we are looking for.

Updated the ng-angular template "kb-feedback-task-modal" per the screenshot but it is not working. We successfully made the Details field read only by adding "readonly" in this location but "required" doesn't seem to be working. 

Thanks!

Hi Harish, I tried your mentioned code above. I am dealing with the same requirements but was not able to make the details mandatory. I there anything I should modify other than this?

Hi Harish,

I'm working with Megan on this.  I've cloned the Knowledge Article Content widget, and I added the code you provided.  I then added the cloned widget to the "kb_article_view" page, and removed the OOB "Knowledge Article Content" widget.

Now, when I click on the "No" button next to "Helpful", I'm getting this error.

Initially the submit is greyed out but if i select any reason the submit button gets available to click

I want it to be clickable only after entering 50 characters in details.
Thanks for any help.
