help with selecting roGridScreen

help pliss

If loading the movies is taking a long time, then your best bet is probably to make the web request asynchronously, so you're not blocking the UI during the request.

and how it would have this function

   
 jsonAsString = CreateObject("roUrlTransfer")
    jsonAsString.SetURL(URL()+"/movie.php?cat="+HttpEncode(category))
    json = ParseJson(jsonAsString.GetToString())
    return json.Videos

please help with this so we can select without having to wait to load the Seciones

any suggestions to achieve the goal I'm looking to selecionar without having to wait for all content carge

who can help me

To make the API requests asynchronously, you'll basically need to use ifUrlTransfer.AsyncGetToString(), then listen for roUrlEvents in your event loop. Once you get the result back, you can then set the contents for the grid screen row(s).

Alternatively, you could opt to work with SceneGraph instead, and utilize the Task node for retrieving your content.
