How to remove a index(a data property) from a data tiddler?

I know I can add and modify the data property of the data tiddler using the setIndex of the ButtonWidget, but I didn’t find a widget or message that can remove the data property.

Is there a way to do this? I need to create a button that will delete the specified data property of the specified tiddler when I press it.

Thank you very much!

When you specify an $index param (the property name), but omit the $value param, it will delete the indicated property.

<$button> remove someindex
   <$action-setfield $tiddler="SomeTiddler" $index="someindex" />
</$button>

-e

@EricShulman It works, thank you!
