I think there are a couple of things you can try to get this. One of the easiest is placing the image above datagrid 2 and then use styling to place it within the header part of datagrid 2.
I think with css position:absolute you can get there.
Hope this helps!
This is not a standard option in the Datagrid2 widget.
Alternative option is to:
- add a classname to the Datagrid2-element;
- add this class to your main.scss (or any more specific .scss-file)
- use ::before to add this image
// Class added to your Datagrid2
.myDatagridWithImage{
.column-header:first-child::before{
background-image: url(images/yourimage.gif);
}
}
