Cell expand event

Hello, Massimo!
 
Thank you for reaching out to us.
 
Kindly note that Flexmonster has a reportchange event. It can be triggered by a list of API calls/user actions, including expands and collapses of data.
 
To check if the data was expanded, we suggest the following approach:
 
1. Store the previous expands using the getReport() API call:

const previousExpands = flexmonster.getReport().slice.expands;

When there is no expanded data, the value will be set to undefined.
 
2.Use the callback of reportchange event to compare the previous expands object with the current one:

flexmonster.on("reportchange", () => {
   if( !_.isEqual(previousExpands, currentExpands) ){...}
});

Please note that this approach would notify you about both expands and collapses of data. You're welcome to make further improvements if needed.
 
We have prepared a JSFiddle example for illustration: https://jsfiddle.net/flexmonster/3of7qm2v/.
 
Hope it helps. Feel free to ask if any further questions arise.
 
Regards,
Solomiia
