Hi kobifrankental,
You have a point, we do not have this option and should add it.
What you can do for now, is to use wix-data APIs and the dopdown APIs to get the list of players from the collection to the dropdown. Something like
Should be something like the following
import wixData from 'wix-data';
$w.onReady(() => {
wixData.query('PLAYERS')
.find()
.then(res => {
let options = res.items.map(player =>
{label: player.playerName, value: playerId});
$w('#DROPDOWN').options = options;
});
})
