Hi,
JavaScript will work on Dropdown select option.

Event will be “Onchange” in dropdown.

Onchange event will trigger JavaScript code and get the selected value and same event we can disable and enable other fields in form.

Thank You!

Hi @Vajrang,

I have followed same steps mentioned in the video, but I can see after selecting value from the dropdown with JavaScript code, the do block is getting executed 4 times.
How to avoid multiple execution of do block.

Hi @Vajrang,

Can you please let me know where can I disable the submit on change option in dropdowns.

Or are you referring to the script written for the dropdown as below -

const updateOnChange = instance.updateOnChange;
instance.updateOnChange = function(flags, changed) {
if (flags.modified) {
instance.emit(‘dropdownChanged’,‘drop’);
}
return updateOnChange.call(instance, flags, changed);
}

If anything needs to be changed in the script let me know. It will help me very much.
Thanks in advance.
