Questions re. Property Inspector

  1. Is there a way to remove Data binding ? I can change the binding - e.g. to a different data source or different field - but I can’t see a way to reset the widget to being unbound.

  2. What is the fourth tab in the PI ?
    I know the tabs are “general properties”, “responsive layout” and “Data binding” - but can’t find what the fourth tab is (and can’t guess what the icon is trying to tell me).

  3. What does it mean to set “float label” to ‘none’? Isn’t that just the same as turning “show label” off?
