shiny - R SelectizeInput - similar solution of ChoiceValues ChoiceNames?

Question

I am working on a small R/shinydashboard project where I have to deal with ID and names: e.g. Warehouse_ID = 1, 2, ... --> Warehouse_Name = Toronto, Berlin,... Since I generated these values from a dataframe, I used:

list_dc_id = unique(dc$id) and list_dc_name = unique(dc$city)

I want to use list_dc_id and list_dc_name to generate the value and shown name with SelectizeInput/updateSelectizeInput(Server=TRUE).

I was able to use checkboxGroupInput with ChoiceValues ChoiceNames to do a check box, however, I am searching for a solution with selectize. I saw some other help pages but unfortunately wasn't able to fully understand the solution. Thank you in advanced!

Answer 1

From ?shiny::selectInput:

choices: List of values to select from. If elements of the list are named, then that name — rather than the value — is displayed to the user.

So you have to do choices = setNames(list_dc_id, list_dc_name).
