When I create a multi select input where i can select resources and I want the output to be a link to that resource. How can I get to link to read/show the title of the page i'm linking to? I can't find any info about that.
I've tried [[*pagetitle]], but then the link text is the pagetitle of the page i'm currently on.
Assuming your TV outputs the id of the resource you want to link to, you can use getResourceField:
<a href="[[~[[*yourTV]]]]">[[getResourceField? &id=`[[*yourTV]]` &field=`pagetitle`]]</a>
