Widget installation - script requires firing JS function

“i guess you need to contact bubble and ask them how to fire a JS function when a form is submitted or a button clicked
maybe they have some option for that 99.9% of websites on the internet when submits data uses the element
they don’t use that for some reason”

Quote from widget/ script creator…

Can anyone help with this?

Check out the Toolbox plugin (https://bubble.io/plugin/toolbox-1488796042609x768734193128308700). You can fire a JS function from a workflow using that.
