I know this is an old post, but I just got to start playing around with ArcGIS Online and this is tremendously helpful to me. Thank you so much.
When you 'Configure Pop-up' in AGO, under the 'Pop-up Contents' you have an option to Display A custom attribute display. Once you have that option selected you click the large green 'Configure Button' and you can configure the way your pop-up looks. Along the top ribbon at the far right of the Custom Attribute Display window there is a '+' button and you can use this to see what attributes you have in your shapefile. So to create your custom pop-up you can write:
price = $ {price}
parcel = {parcel} - this is an example
And then add what other attributes you want in your pop-up as well below this one. And as I mentioned, to include the other attributes just use the '+' button so you don't have to remember what all of your attributes are.
I hope this helps.
So bringing this thread back...
I like the workflow, however is it possible to use the styling of the stock pop-ups? For my parcel layer, I simply want to add a $ sign before any monetary values, but would like the style of this pop-up to match all the others.
I see the ‘View HTML Source’ but I am not well-versed in HTML and CSS enough to craft it. Has anyone attempted this before?
Thanks,
Jarrett
