validation – Should comboboxes/radio groups be marked “required” in a form?

Suppose you have a web form, with some fields being optional and some being required.

One of these fields is a combobox or radio button group, for which a valid default option is pre-selected and it is not possible to “un-set” this field.

In other words, this field is always valid for submission, but potentially not correct, and I can’t have users “glossing over” that field as many will with all of the “optional” fields.

Should this field be marked “required”?

Note: I would prefer to keep the default pre-selected option, because this value is the correct value for more than half of the use cases by volume.

Where are invoiced + shipped orders marked as complete?

In some (not all) cases, I want to set the status of an order to a new custom status after it has been shipped.

Where in the core code is an order updated to complete once it has been invoiced and shipped?

url – LinkedIn connection marked unsafe

From time to time my LinkedIn connection gets marked as unsafe: no green lock next to the URL.

First, I believed this was a browser issue, but after I switched to another browser, the warning did not disappear (for now, my browsers are Opera and Chrome).

First, connection is always safe, but once I enter job search section and start scrawling through job offers, every now and then, although not often, the safe connection status turns into unsafe. Any one has an idea of what may cause such change?

Thanks for your attention.

The enclosed images further illustrate my question.

How to download the marked web page in the Chrome browser as a pdf page?

Most web pages change or are removed very often on websites. To avoid this, I would like to download them as PDF files and store them for future reference. I can do it manually. But very exhausting.

Is there any plugin or shape? The moment we mark the article in the browser, it will automatically be saved as a PDF on the hard disk or in any cloud.

Thanking you ,

Cheers
