Can I remove blank fields on my notification email?

[HowDoYouWannaDoThis]

I have a submission form that my users needs to fill-up. I also created an email notification that contains all the fields on my form. The problem is that some fields can be blank and I would like to remove those fields to make the email shorter. Is there a way to this in caspio?

You can create a virtual field on your submission form and use a bit of script just like below:

COALESCE('Item1: '+NULLIF('[@field:item1]','')+'<br/>', '')+
COALESCE('Item2: '+NULLIF('[@field:item2]','')+'<br/>', '')+
COALESCE('Item3: '+NULLIF('[@field:item3]','')+'<br/>', '')+
COALESCE('Item4: '+NULLIF('[@field:item4]','')+'<br/>', '')+
COALESCE('Item5: '+NULLIF('[@field:item5]',''),'')

This will remove all fields that doesn't contain any values. Once that is done, go to your email notification at the end of the DataPage configuration and put the Virtualfield in body. Don't forget to set it to HTML for the '<br/>' to work. This setting will show 1 field or item per line. If you want to show every item in one line then change <br/> to space or comma.
