The reason you may not see the "Open in new tab" option in the context menu when right-clicking on the anchor tag is because of the way Angular handles navigation using [routerLink].
When you click on a link with the [routerLink] attribute, Angular intercepts the click event and uses its router to navigate to the specified route without actually navigating to a new page. This means that the context menu options related to opening links in a new tab or window are not applicable in this case.
To open the link in a new tab or window, you can still use the browser's built-in options. You can do this by either:
Hold down the Ctrl (Windows) or Cmd (Mac) key while clicking on the link. This will open the link in a new tab.
Right-click on the link and select "Copy link address" or "Copy link location" from the context menu, then open a new tab or window and paste the link into the address bar.
Note that if you want to explicitly allow opening the link in a new tab or window, you can add the target="_blank" attribute to the anchor tag, like this:
<a class="someClass"
[routerLink]="[PATH, item.id]"
[queryParams]="{category: item.parent.category, childItem:item.parent.childItem}"
target="_blank"
>
{{item.parent.name}}
</a>
However, using target="_blank" can be a security risk if the link is controlled by an attacker. This can lead to what is known as a "tab-nabbing" attack, where the attacker can replace the content of the new tab with malicious content. Therefore, it is generally recommended to avoid using target="_blank" unless you trust the content of the link.
