Hey,
Lets say that you have 4 checkboxes, you can use the following code:
$w.onReady(function () {
for(let i=1 ; i < 5; i++){
$w(`#checkbox${i}`).onChange(()=>{
const checkBoxes = ['checkbox1', 'checkbox2', 'checkbox3', 'checkbox4'];
let filtered = checkBoxes.filter(item => item !== `checkbox${i}`);
filtered.forEach((checkbox)=>{ $w(`#${checkbox}`).checked = false; });
});
}
});
However, I recommend using for that purpose radio buttons which have the same functionality…
Good luck,
Tal.
