smooth signature mandatory field

hi

I have a smooth signature in my form and I can't see where I can make this field mandatory. every time I double click on it - it brings up widget settings but with no real options to choose from? 

Hi,

You can make the signature element field mandatory by following these steps;

1- Choose the 'Signature' element and click the gear icon which named 'Properties'

2- In the properties, you'll able to see a dropdown named 'Required'. When you choose that option as yes, it will make your signature area mandatory.

If you require more information please let us know.
