We want to introduce a custom amount field to the mobile banners.
- The amount option of 75 Euros is removed in both banners.
- A custom amount field is added to both banners. Its placeholder text is "other" (en) and "anderer" (de).
- The field allows users to enter an amount of their choice.
- The field resembles the select/deselect behaviour of the other amount options.
- Depending on whether that is applied to the current control or variant:
- The breakpoint for reducing the amount option column count to 2 is increased to 450px.
- In viewport widths below 450px the amount options column count is reduced to 2 columns.
