Hey @enrique.klix,
To make a form where users can only choose one option per category (exclusive single selection, like radio buttons):
The proven native way I’ve used in surveys and forms:
-
Create a number property in your collection for each category (e.g., “Mental Choice”, default 0).
-
Use buttons for the options (each button has two states: State 1 as Default, State 2 as Selected):
-
State 2 (Selected) visibility: Current Collection > Mental Choice = 1 (for first option), = 2 for second, etc.
-
State 1 (Default) visibility: Current Collection > Mental Choice ≠ that number (or leave as default when State 2 is hidden).
-
On action: Update Current Collection > Mental Choice to that number.
-
This ensures only one button shows State 2 (Selected) at a time, others stay in State 1 (Default).
No extra actions needed.
If you prefer the toggle look:
-
Toggles are bound to boolean properties, so for exclusive selection, use separate booleans for each option.
-
On each toggle actions, add an action to set the selected boolean to true and the others to false.
This works, but with 6 options per category, it means more actions on each toggle. The button method with number property is cleaner and scales better for multiple categories.
Repeat for other categories with separate properties.
