Is there a Likert control?

I mean you could just use the New-UDRadioGroup wrapper for New-UDRadio:

New-UDRadioGroup -Label "Day" -Content {
    New-UDRadio -Label Monday -Value 'monday'
    New-UDRadio -Label Tuesday -Value 'tuesday'
    New-UDRadio -Label Wednesday -Value 'wednesday'
    New-UDRadio -Label Thursday -Value 'thursday'
    New-UDRadio -Label Friday  -Value 'friday'
    New-UDRadio -Label Saturday -Value 'saturday'
    New-UDRadio -Label Sunday -Value 'sunday'
}

Example:



See:

If you wanted horizontal, I’m sure there’s ways to modify the css/style otherwise you could just code it using New-UDGrid and then some onchange handlers of New-UDRadio but the latter probably isnt a very efficient way of doing it although I’m sure it would work.

Alternativly you could follow the guide for creating a custom component and use an existing react likert style package.

You mean something like this?

Or this

Something like this:

This is as close as I can find in link 2
A React component that renders a Likert scale (reactjsexample.com)

I did recently put that new website together to compliment what is already documented about building a custom component. I would recommend that if this is what you are after
