R Shiny - Optimize page loading time with updateSelectizeInput

由 走远了吗. 提交于 2019-12-07 23:22:30
问题 Our shiny page has multiple selectizeInput controls, and some of them have long lists in their drop-down boxes. Because of this, the initial loading time is very long as it needs to pre-fill drop-down boxes for all selectizeInput controls. Edit: Please see below example showing how loading long lists impacts page loading time. Please copy below codes and run directly to see loading process. library(shiny) library(shinydashboard) ui <- dashboardPage( dashboardHeader(title = "Basic dashboard"),

how to manually expand a submenu in a shiny dashboard side bar

由 好久不见. 提交于 2019-12-07 16:45:50
问题 I'm trying to manually expand a submenu in a sidebar in shiny dashboard. The updateTabItems function only works with normal menus, but not with nested menus. Here is basic example (modified from the updateTabItems documentation) to show the problem. If I clicked on 'Switch tab', it switches the menus, but it doesn't expand the first menu that has a submenu. It seems that it only selected the submenu but doesn't expand the tree. library(shiny) library(shinydashboard) ui <- dashboardPage(

问题 Hello Stack Overflow, in recent questions by me I've solved some major issues related to dynamically rendered UI elements and dynamically created observers for those with the help of some amazing people here. see i.e. here: Dynamically rendered UI: how to delete old reactive variables on second run Now I'm building a part of it that dynamically renders textInput fields. The rendering and monitoring shouldn't be a problem because I can apply the same way of coding as for the actionbuttons we

问题 The Problem I am creating a shinydashboard to help a client explore some spatial data.
