At the moment there is no configuration for this. Added in plan.

See documentation https://docs.rukovoditel.net/index.php?p=104
you have to use not echo command

Please reproduce issue in personal demo https://www.rukovoditel.net/demo.php
and give me link to the demo. I will check.
Please do not upload your database. Use default one.

The latest version is 3.5.3. But I think it can be issue with your server or browser. Maybe some security plugin cut off some html/css in your case.

Make sure you have updated database for main version and extension. See instruction https://docs.rukovoditel.net/index.php?p=63

Also check php error log on your server.

Note: 3.5 required PHP>=8.0.2

Found issue. File from archive replace to includes\classes\fieldstypes\
Let me know if it works ok now.

Just select None in dropdown to reset values.

Edit Entity and set flag "Display in Menu"

have no idea what can it be.

Try to rewrite files. The best way is load archive to server an unpack it there.
If not help then ask your hosing support why you have "500 (Internal Server Error)" to include css file. Probably issue with file permission or something like this.
