Separator component to visually emphasize field groups

[christian-konrad]

Is your feature request related to a problem? Please describe

With the new components and text view features, it can get quite difficult to visually differentiate groups of fields/components, as shown in this example.

Describe the solution you'd like

To visually emphasize separate groups/blocks of fields/components, a separator component (a horizontal line) is a simple, but helpful tool.

Describe alternatives you've considered

Support "---" in the text view markdown. But I advise against it, since it is hard to discover. A dedicated component is easier to find.

There exist some alternatives to accomplish visual grouping:

• Provide micro-building blocks (horizontal rule, as you suggest)
• Stack fields (optionally) into groups and clearly separate groups from each other, visually. Also, give groups titles (seen in screen above, too)

It would be interesting which direction you want to go.

@RomanKostka Of interest

As a part of this issue, we're introducing a horizontal separator component.
The component is named "Separator".

To help the user easily differentiate components, we're also updating the icon for the Spacer component that already exists.
