How to do text / text in a Select Bar?

hi guys, simple question,

in the Radzen Select Bar, how do you do a text / text item?

the application renders a text / numeric okay,

but seems to crack it with text / text

actually scratch this, i found how to link it to my dictionary of drop down values which can do text / text

this is working okay for a single entry, however it seems to crash on multi-select
i was hoping to put the values of this into a single text field separated by a pipe, i.e.

monday|thursday|friday|sunday

is there an example of something like this floating around?
