Hi! When the page loads, initialize an empty array called lockedItems to store the locked items. When the user clicks the lock button for an item, get the data for that item and add it to the lockedItems array using wixData.get. When the user clicks the generate button, use the wixData.query function to retrieve all the items from the database and store them in a variable called allItems. Use the array.filter method to remove the items in lockedItems from allItems. Use the shuffleArray function to shuffle the remaining items in allItems. Set the data for the repeater to the first 10 items in the shuffled array using the $w(‘#mainRepeater’).data property.
