Equivalent -- Experience Builder -- Add Data Widget

spence_amzn — Wed, 07 Aug 2024 23:02:41 GMT

Hi folks,

I am hitting a brick wall and cannot for the likes of me find the functionality (native) to be able to add a "Add Data" widget like functionality to dynamically add feature layers to a map? Anyway have tips and/or a pointer to look at?

If you already have the item id for the layer you're trying to add, the process is pretty simple using a portalItem.

If you want users to be able to search for layers in your portal, you can use the portal class and it's queryItems method to grab a list of portalItems

Then you just need to go about adding the portalItem to the map.

If you want users to be able to upload features from files, you'd need to handle the uploading portion and then parse the file contents into a layer.
Feature Layer has good documentation for creating from an array of client side graphics.
