I have a repeat form which has a select field within it that queries a table for its data source, and am trying to filter the select options to remove any values that are already selected in the other repeats. I have found a couple ways to do it (where I create a variable outside of the repeat that receives a value from each select once changed, and the another variable within each array that takes the above array and subtracts the value of the the select within its respective repeat), but while doing this I got to thinking there is likely more simple/straightforward way of doing this, or if not maybe a more “standard” or best practice of achieving it.
