Afraid not - the data attribute setting will only allow one attribute and you need 3 on there.
I added attributes to button plus before people were so adept at adding code so the data name and the value were separated in the settings (remember at that point I was getting grief for having a custom class setting in my stacks from many other devs).
If you want and you can’t make something else look the same then I could add another input “just cause its you!”
Haha - many thanks, Andrew. I’m genuinely touched. But, please don’t bother. The campaign is for a special “Day of Giving” that’s just stateside next week, and one day only. They can have their ordinary-looking button for a day. In fact, I’ll hide it behind a ButtonPlus2 using a PopDrop, so it will still look great on the website.
