Updates the default layout for Payment ElementBreaking changes

What’s new

The default layout for the Payment Element now displays as an accordion instead of as tabs. We also updated the behavior of leaving the defaultCollapsed value undefined, which now collapses when multiple payment methods are displayed.

Why is this a breaking change?

This breaking change affects you if your integration uses the default value, and was designed to rely on a tabs layout instead of an accordion layout. To migrate, either set the layout value to tabs or change your design to match the accordion layout.

If your defaultCollapsed value is undefined and you want to restore the previous behavior, you can set the value to true.

Impact

Using an accordion layout and collapsing multiple payment methods can help improve conversion rates for mobile users.
