Hi @Aditya02 ,

Create onSubmit catalog client script

function onSubmit()

var values = g_form.getValue('variableName').toString().split(',');

if(values.length > 2){

alert('Please select only 2 choices');

return false;

}

}

can we able to do anything , when user selecting of choices itself, instead of before submitting the form.

while selecting itself, he should not able select more than 2 choices.

You can use onClick for it and restrict adding more than two

[Aditya02]

There is No such Onclick type, Only has these types:

  1. Onchange

  2. Onsubmit

  3. Onceledit

  4. Onload
