I'm using Select 2 Tags in a field with the parameter $col["formatter"] = "select" to show values instead of keys in the column and it works fine. But when I export to Excel or PDF this doesn't work and keys instead of values are displayed.
I have read in other posts that this problem can be solved with the use of "on_render_excel" and "on_render_pdf" but I cannot find specific code to handle multi-select fields. Can anyone help, please? Thank you very much
