How to reference the parent index in a nested list view

[pablo.estrada]

• Goal: I have a parent list view (listView1) and a nested list view (listView2)

My goal is to have a title (in the nested list view) that provide the parent index and the child index, ex (1.0, 1.1)

Problem:

Within the nested list view, I am only able to reference the index of the child list view (listView2). How can I also reference the index of the corresponding parent list view (listView1)?

Hi there @pablo.estrada,

It's been a while since I use this, and I'm not sure if it works in the same way as it used to work in legacy litsViews, but you can use the {{ ri }} variable.

I made a quick test and it seems to return both the index of the parent listview and the current item. If you use {{ ri[0] }} you'll get the index only of the parent listview.

Hope this helps!!

Hello @pablo.estrada

I understand you issue ,
For your functionality you have to use the js query of retool for create the json perfectly.

You have to use js code :

const numbers = Array.from({ length: 9 }, (_, i) => i + 1);

const result = numbers.map(num => {
    const s = [];
    
    for (let i = 0; i < 4; i++) {
        s.push(`${num}.${i}`); 
    }
    
    return { m: num, s };
});

return result; 

and use this js query data in listview1 and listview2 like this

In listView1 use this query-data data source : {{ query1.data.map( item => item.m ) }}

in listView2 use this query-data data source: {{ query1.data[i].s }}

Thank you .
