Filter question from newbee

[Rien van Ham]

Hi all,

I am totally new to WiiM so perhaps this question is already been discussed here (but I can't find it).

I have a Wiim Ultra. I have around 45.000 songs on my Synology NAS which runs Mediaserver/

In the WiiM Home App I see the server and can browse the songs.

Now my question:
If I select a genre (e.g. "dance") I get a huge amount of songs. Then, if I fill in a search-criteria in "Find on this page" (e.g. "Top 40") I get the wanted songs.

But:
1: if I play a song of it, songs which are not present in the filtered list, are played after it;
2: how can I make a playlist of the filtered titles?

Thanks in advance,
Regards,
Rien.
