Is it possible to use sort drop-down menus on the Export Html web page like in Excel? It doesn't appear when I export the file from MP3Tag.
You would have to edit the source code from the *.mte export configuration file.
-> Press the Edit icon on your selected export configuration file

I'm not sure if sorting dropdown menus (or their contents?) is even possible.
You could have a look at this sortable example
Maybe you can adjust this code to your needs?
Perfect...works great! Thanks a million!
Would you be able to add MediaType to the list to sort and all others? I made changes to the HTML part but my list appears underneath the one with no changes (both are displayed). Also, I tried to change the header color from orange to yellow, but both headers show as orange.
You need to add this information at two locations:
a) Add a new column with <th><button class="th_css">MediaType</button></th>
b) Add something like %MEDIATYPE% to the line where you $loop through the data
You need to change the colors in the CSS <style> part of the HTML-Code.
Search for "orange" and replace it with "yellow" or whatever color you want to see.
Thanks, that's what I needed to know.
