<div
[style.display]=
"person.id === -1 ? 'grid' : 'none'">
First Save New Person,
then proceed.
</div>
Similar to the [ngclass] attribute; here we deal directly with the display style instead.
If the new person (id = -1) is shown then this message is displayed. Otherwise when person.id is other than -1 the display is set to none! This allows the remaining page to be rendered because, this element renders with a width of 500em pushing everything off the page. Probably not good practice but works.
Works like a charm!
