Is it possible add button with link to other page into block setting? I mean Here.
I need a button in the content or settings section, which brings me to another page on click.
Thank you
You could create a view for that block type (just as you would for any other block type) and insert the link there. Editors would be able to click the link while in on-page editing mode for the settings block.
If you want to insert it into the Episerver UI, you could create a custom Dojo widget.
