Selectize - allow duplicate values

[cklar]

Hi -

I'm trying to achieve that I can select one value multiple times within a selectize-box. E.g. if the options are A,B,C I want to be able to select A,A,A,B,A and so on. It's exactly the same problem as in:

Allow duplicate values in an input

However it seems that the duplicate variable option (duplicates: true) is not available when setting it through options within R shiny (and it doesn't seem to be in the selectize.min.js file either).

Anybody come across a solution here? Will I need to hack the selectize.min.js file?

Thanks!

Regards,

Christian
