Marked the selected Item by the other user/wix window.

[jeffersonuy]

Hi, I have this problem scenario.
Example: I have 2 users using different PC , when they both access the same page, user1 selected an item from a dropdown element, and when user2 selects an item from the dropdown the item selected from user1 must be hidden or flag as “being selected by the other user”. How am I be able to to that? Any ideas are greatly appreciated. Thank you in advance. Unfortunately I don’t know how to use wixReal-time

Why this is so hard to achieve Why wix doesn’t have this functionality?
Can this be done using wix-realtime? Below is my work around but it has a problem.

$w.onReady(function () {

    setInterval(function(){ $w('#dataset1').refresh(); }, 500);
});   
export function dropdown1_change(event) {
    wixData.query("myDatabase")
    .eq("name", $w("#dropdown1").value)
    .find()
    .then( (results) => {
     let values = results.items[0];
        values.inProgress = 2;
        wixData.update("myDatabase",values)
    }) 
    $w("#input2").value = $w("#dropdown1").value;
    $w("#input3").value = $w("#dropdown1").value;
    $w("#dropdown1").value = "";
    $w("#dropdown1").resetValidityIndication();
}


export function cancel_click(event) {

    wixData.query("myDatabase")
    .eq("name", $w("#input3").value)
    .find()
    .then( (results) => {
     let values = results.items[0];
        values.inProgress = 1;
        wixData.update("myDatabase",values)
    }) 
 
    $w("#dropdown1").value = "";
    $w("#input2").value = "";
    $w("#input2").resetValidityIndication();
    $w("#dropdown1").resetValidityIndication();
}

export function approved_click(event) {
    wixData.query("myDatabase")
    .eq("name", $w("#input3").value)
    .find()
    .then( (results) => {
     let values = results.items[0];
        values.inProgress = 3;
        wixData.update("myDatabase",values)
    }) 
    $w("#dropdown1").value = "";
    $w("#input2").value = "";
    $w("#input2").resetValidityIndication();
    $w("#dropdown1").resetValidityIndication();
}
