How to change one item in a repeater

You didn’t write if the repeater is connected to a database or fed manually.
Let’s assume it’s connected to a database where you have a field key named isLeased that can either get the value true or the value false.
In that case you can make your textbox (let’s call it “statusText”) collapsed by default and expand it in case isLeased === true:

 $w("#repeater1").onItemReady( ($item, itemData, index) => { 
itemData.isLeased ? $item("#statusText").expand() : $item("#statusText").collapse();
})
