Sticky titles in expansion grid

[AlexBabii]

Hi, I'm using Smartclient v12.1p_2023-08-16/Pro. I was wondering if it's possible to make sticky titles in expansion grid. What i mean by that if it is possible to make the selected expanded item sticky so when we scroll the grid up or down we will always see it on top. You can see the example on top of how my grid looks like. I would really appreaciate if someone could guide me through this.

We would approach this as "popping out" the record as a separate record rendered by a second ListGrid, which has the same settings as the main grid but only shows the one record.

You could combine both grids into a VLayout, or define the "popped out" grid via listGrid.gridComponents, keeping it hidden when there is no "popped out" record.

Note you will need to think through how you want selection, editing, frozen columns and other features to work given this special record.
