Is there any option to use "Select All" widget for calculation fields?

Hi,

Is there any option to use "Select All" widget for calculation fields? 

I would like to use this widget or similar to calculate values in similar way as we have in drop-down widget (Options & Surveying).

Thanks

I'm not sure what you mean by "Select All" widget for calculation fields. I also checked your form ( https://www.solarpricediscovery.com/solar-panels-calculator/ ) and I didn't find any fields or labels that say (Options & Surveying). Could you please clarify to us a bit more in detail so that we could further check?

If possible, please try adding a screenshot image of your requirement to this thread. Open this thread: https://www.jotform.com/answers/1150539 on a browser and follow the steps in this guide on How to add screenshots/images to questions to the support forum?

We'll wait for your response.
Regards.
