How do you connect a custom element to data from a collection?
On the support page (https://support.wix.com/en/article/custom-element-faqs) its says the following:
'Can I Connect Custom Elements to Data in a Collection?
Yes, you can connect custom elements to collections using Corvid's [Data](https://www.wix.com/corvid/reference/wix-data.html) and [Dataset](https://www.wix.com/corvid/reference/wix-dataset.html) APIs.'
I couldn’t figure out how it works.
See the Dropdown Custom Element example which uses the results of a database query to populate a custom dropdown element.
Ok, the live demo works but when i go to edit the example the preview does not work because it has an async / await function in the custom element.
Also once i chose an option in the drop down how do I get the value in my page file
//Edit
I have got the dropdown working in preview now. I just need to be able to access the chosen value of the dropdown in the main page file so i can write it to my database
