Original forum post: Remove duplicates from connected dropdown options
About this example
This example is a variation of the original Search a Database example, by adding the code that @Jeff (Wix) contributed in the forum article Remove duplicates from connected dropdown options. Instead of getting dropdown options from a table or dedicated collection of options, the options can be retrieved from a regular data collection with the duplicates being removed before assigning to the dropdown list.
