Hey @papuha

Consider using transforms https://plot.ly/r/#transforms with the dropdown:

library(plotly)    

p <- iris %>%
  plot_ly(
    type = 'scatter', 
    x = ~Sepal.Length, 
    y = ~Petal.Length,
    text = ~Species,
    hoverinfo = 'text',
    mode = 'markers', 
    transforms = list(
      list(
        type = 'filter',
        target = ~Species,
        operation = '=',
        value = unique(iris$Species)[1]
      )
  )) %>% layout(
    updatemenus = list(
      list(
        type = 'dropdown',
        active = 0,
        buttons = list(
          list(method = "restyle",
               args = list("transforms[0].value", unique(iris$Species)[1]),
               label = unique(iris$Species)[1]),
          list(method = "restyle",
               args = list("transforms[0].value", unique(iris$Species)[2]),
               label = unique(iris$Species)[2]),
          list(method = "restyle",
               args = list("transforms[0].value", unique(iris$Species)[3]),
               label = unique(iris$Species)[3])
        )
      )
    )
  )
