I cant seem to be able to add PDF Documents to my database collection. Totally in love with Wix Code as it has made developing my website a zillion times easier 
but need to be able to add PDFs to the database collection and also I notice when I put a link to an online Page which is a PDF it doesnt go. It instead tries to open email client on my computer.
Hi Visas,
Wix Code doesn’t support storing PDFs in a collection…yet. It is in our backlog and coming soon, so stay tuned.
Regarding linking to an online PDF, I gave it a try and it worked for me. I put the URL in a text field in the collection. Note that the URL has to include the http:// or https://. Then I used the Connect to Data panel on a button and set “Link connects to” to the text field where I stored the URL. Clicking on the button in the published site opened the online PDF.
Hope that helps.
Thanks for this Jeff, I’ll give it a shot now… Thats very helpful
