You need to follow three steps:

1. Create a context variable on the onvisible property of the form on MultiPage: UpdateContext( { showAllFields: false } ), This creates a variable showAllFields which is set to false.

2. Select the datacard you want to hide on default and set the visible property to showAllFields, thiswill show the datacard when the variable is true and hide it when it's false.

3. Add a button and put the following on the onselect property: UpdateContext({showAllFields:!showAllFields}). This will switch the variable from false to true if it's false and from true to false if it's true.

To Navigate between screens:

   Navigate( Screen [, Transition [, UpdateContextRecord ] ] )

Screen - Required. The screen to display.

Transition - Optional. The visual transition to use between the current screen and the next screen. See the list of valid values for this argument earlier in this article. The default value is None.

UpdateContextRecord - Optional. A record that contains the name of at least one column and a value for each column. This record updates the context variables of the new screen as if passed to the UpdateContext function.

So in your case if you don't want to pass any context variable, just use:

  Navigate( Page2, ScreenTransition.Fade ) on button select

Page2: Screen Name ScreenTransition: Effect used to switch the screens.

In Order to go back to previous Page use following:

      Back(ScreenTransition.Fade)

or you can use

      Navigate(page1, ScreenTransition.Fade)
