Retrieving data from nested repeats

My question is… can I use Data Detail to retrieve data from Nested Repeat Regions?

I have a server side nested repeat that looks like this

In my app, I have a dynamic repeat row which displays the Category, and then each product within that category along with an add to cart button. If someone presses the button, it then opens a modal window to ask for options such as size, colour etc.

<button class="btn btn-warning" id="with_options" dmx-hide="set_price" dmx-on:click="options.data_detail.select(id);options.show()"><i class="fa fa-plus"></i></button>

The problem is, I can’t seem to get the product details showing in the Modal window. The best I’ve managed to get is the category details.

<dmx-data-detail id="data_detail" dmx-bind:data="menu.data.category.product" key="id"></dmx-data-detail>
          <div class="modal-header">
            <h5 class="modal-title"> {{data_detail.data.name}} </h5>

Hi @max_gb, did you manage to fix this. I’m also not seeing the child level query (within repeat), same issue.

I did get this working in the end as the issue was being caused with the dynamic data picker. I had to change my expression to modal1.data_detail1.select(id) manually.

Not live at the moment. If you post an example link maybe we can look into it?

Thanks mate, I figured it out… the dynamic data picker is still flawed… I figured out what’s done manually by you to get the nested data… Thanks again!
