Query the database and assign the retrieved data to the repeater with Wix Velo

  wixData.query('YourDatabase')
  .contains('YourFieldname', variableValue)
  .find()
  .then(results => {
    let items = results.items;
    console.log(items);

    
    if (items.length > 0) {
      //do something with the retrieved items

      $w('#repeater1').data = filteredResults;
      
    }
        })
        .catch(error => {
            console.error('Error fetching data:', error);
           
        });

This is just for showing the basic data retrieval from the database. Make sure that you have connected the repeater elements to the correct dataset.
