Delay the rendering of element

Can I delay the rendering of the element?
I want to display data asynchronously received.
Currently, the rendering is complete the moment the data is retrieved from the server and the label is drawn to the value in the original xml.

First of all, please make sure that topics are self contained. If you’re referring to some other topic, in this case this one, without making that clear, people will be confused.

Why do you start the import before having the data in the first place?
