Hi all, could anyone advise me how to customise drop down list values, so the drop down values are generated/displayed in multiples of six.

Values Example: [6,12,18,24] etc.

Thanks in advance for your help and advice.

You need a function to create such array of values, like this:

function fillDropdown(numberOfItems, multiplier) {
    let arrayDropdown = []
    for (let i = 0; i < numberOfItems; i++) {
        arrayDropdown.push({ value: i * multiplier, label: i * multiplier })
    }
    return arrayDropdown
}
