Fullpage scrolling with map

[mschnetzer]

Hi, first of all, thanks for the amazing implementation of fullPage in R!

I'd like to have a slide with a fullpage map where scrolling does not zoom but scroll to the next slide. To avoid zooming, I set the leaflet options. But scrolling to the next slide does not work. Is there any workaround?

Thanks a lot!!

Here is some example code:

library(shiny)
library(fullPage)
library(tmap)

data("World")

ui <- 
  fullPage::pagePiling(
    sections.color = c('#fff','#000', '#fff'),
    menu = c("Full Page" = "Link1",
             "Map" = "Map",
             "Another Full Page" = "Link2"),

    fullSection(menu = "Link1", center = TRUE, tags$h1("FULL PAGE 1")),

    fullSection(menu = "Map", tmapOutput("fpmap", width = "100%", height = "100%")),

    fullSection(menu = "Link2", center = TRUE, tags$h1("FULL PAGE 2"))
  )

server <- function(input, output, session) {

  output$fpmap <- renderTmap({
      tm_shape(World) +
      tm_view(set.view = c(11.57549, 56.13743, 4),
              control.position = c("right","bottom"),
              leaflet.options = list(minZoom=4, maxZoom=4,
                                     zoomControl = FALSE, dragging = FALSE,
                                     keyboard = FALSE)) +
      tm_polygons("HPI")
  })
}

shinyApp(ui = ui, server = server)

Yes this is a recurring issue because it's not clearly documented. You can keep scroll from switching page/slide with an option: specify the id (probably fmap in your case) of the element to said option.

An example for a drop down here

Let me know if this helped

Dear John, thanks for your fast response and your support.

I am not sure if your example meets my problem, as I understand that in this example scrolling is prevented for some elements while I would like to activate it for the map. I have a full page map (with disabled zooming) and I would like to scroll to the next page with my mouse wheel. I have edited my example code above to a full working example. I hope you will see, that sometimes scrolling in the map is working, but as soon as I "hit" a label in the map or click somewhere on the page, the mouse wheel is not scrolling anymore.

Thanks again :)

Apologies, I misunderstood your question. I'm not sure how to solve this as it seems to be on tmap's side, zoomControl = FALSE disables the scroll completely.
