Added id's to menuItems and menuSubItems

[metanoid]

Please see issue #114

I could not understand how to implement the suggestion of user @funnng as shown here

To this end, I tried my hand at adding id's directly to the menuItem and subMenuItem functions in the shinydashboard code.

I ran the tests, and everything seems to be working. However, I have absolutely no idea what I am doing. Do not merge this pull request until thorough testing has been done by competent persons.

Thanks.

You need to fix R docs (in man folder) in order to pass travis tests. See here: https://travis-ci.org/rstudio/shinydashboard/builds/112231436#L1353

If you are using rstudio (i hope) + devtools package, then just do CTRL+SHIFT + D. And then push again.

Hopefully Winston (@wch) will take a look on both PR soon. (I would like to open a third one but waiting to have the first one being merged).

Also added id to box, valueBox, and infoBox

This would be great to have merged into the dashboard. I am trying to add Google Analytics tracking to a shiny dashboard and it is proving incredibly difficult to do so without IDs being available. It would be great to add this to the tabPanel object too so I can track if someone clicks on the various panels.

Did we fixed the tabpanel id identification ? Current issue is that tabpanel has random value with no id and can't be associated with event action and hence can't logged that event click information in google analytics.

@metanoid, I came across an issue with the infoBox id in your version of shinydashboard today.

Running this example:

library(shiny)
library(shinydashboard)

ui <- dashboardBody(
  infoBox(title = "Test")
)

server <- function(input, output) {}

shinyApp(ui = ui, server = server)

throws the following error:

Error in tag("div", list(...)) : promise already under evaluation: recursive default argument reference or earlier problems?

The app works if we explicitly add an id as in id = "test".

The documentation has:

id An optional id for the element

so it seems to be behaving strangely.

Thanks @Eli-Berkow , fixed - good catch!

Any chance of this getting merged. Looks like a great addition and becomes very nessecary as you try to add any kind of functionality beyond the basic stuff
