Hello Guys, Is it possible to eliminate / filter options in a dropdown comparing another dropdown?

Allow me to show another way of doing this, assuming that your dropdowns are manually connected instead of coded.

//Function that filters repeated items from dropdowns
const filter = (list, listToFilter) => {
    return listToFilter.filter(({ label }) => !list.some(item => item.label === label))
}

$w.onReady(async () => {
    //Wait for the dataset A to be ready
    $w('#datasetA').onReady(() => {
        //Wait for the dataset B to be ready
        $w('#datasetB').onReady(() => {
            //Get the dropdown values
            const dd1 = $w('#dropdown1').options
            const dd2 = $w('#dropdown2').options
            //Filter the values
            const filteredDD = filter(dd1, dd2)
            //Feed them to the dropdown that needs filter
            $w('#dropdown2').options = filteredDD
        })
    })
})

Best regards.
