I would like to know how to make one repeater filter the other

If the user clicks on a button in one repeater, it will filter the content of the other if they are both connected to different data bases

Hello flamanyoman,

take a look here…

You will need to loop trough the first repeater to find the value for filtering process in dataset-2.
After filtering process in your second database, you just simply push the result to your second repeater.

How to loop trough repeater?

$w("#myRepeater").forEachItem( ($item, itemData, index) => {
2  let repeatedElement = $item("#repeatedElement");
3  let nonRepeatedElement = $w("#nonRepeatedElement");
4  let itemDataValue = itemData.someProperty;
5  let isEvenItem = index % 2 === 0;
6} );

Copy Code

1$w.onReady(function () {
2  $w("#myDataset").onReady( () => {
3    $w("#myRepeater").forEachItem( ($item, itemData, index) => {
4      if(itemData.boolField){
5        $item("#myText").text = "Yes Ma'am!";
6      }
7      else {
8        $item("#myText").text = "No way!";
9      }
10    } );
11  } );
12} );

Or some code of my own…

$w.onReady(function () {
    $w("#dataset8").onReady( () => {
        $w("#repeater1").forEachItem( ($item, itemData, index) => {
            $item("#BTNedit").onClick((event) => {  
            console.log("you clicked " + itemData._id)
            $w("#dataset8").getItems(index, 1)
                .then( (result) => {
 let items = result.items;
 let totalCount = result.totalCount;
 let offset = result.offset;
                    console.log(items)
                })
                .catch( (err) => {
 let errMsg = err.message;
 let errCode = err.code;
                });
            });
        });
    });
});

These are all just examples, so you will have to modify code for your own project.
