How do I populate a repeater with new data?
The most common way to populate a repeater is as follows:
-
Set the repeater’s data using the data property. This triggers the second step for all items in the data array with a new ID.
-
Populate the repeater with data from the new items using the onItemReady() function.
If you just want to call data from a dataset, then just use getCurrentItem from Wix Dataset.
