Multiple conditions in condition panel R shiny

Question

Is it possible to have multiple conditions when using conditionpanel in aa r shiny app? I want to hide a particular UI component for a couple of tabs. Below is what I am trying but it doesn't seem to be applying when I have multiple conditions:

library(shiny)
library(shinyWidgets)
library(shinydashboard)
library(DT)

sidebar <- dashboardSidebar(
  sidebarMenu(id = "tab",
              menuItem("1", tabName = "1"),
              menuItem("2", tabName = "2"),
              menuItem("3", tabName = "3")
  )
)
body <-   ## Body content
  dashboardBody(box(width = 12,fluidRow(
    fluidRow(  column(
      width = 3,  textInput("text1", label = h5("Min"), value = "1")),
      column(
        width = 3, textInput("text2", label = h5("Max"), value = "2")),
      conditionalPanel(
        condition = "input.tab !== '2' || input.tab !== '3'" , column(
        width = 3, textInput("text3", label = h5("Max"), value = "3"))),
      column(
        width = 3, textInput("text4", label = h5("Max"), value = "4")))

  )))

ui <-   dashboardPage(dashboardHeader(title = "Scorecard"),
                      sidebar,
                      body)

# Define the server code
server <- function(input, output,session) {

  output$op <-renderDataTable({
    df_format()
  })

}

shinyApp(ui = ui, server = server)

As @RyanMorton said, the problem was that you used an OR when you should have used an AND:

condition = "input.tab !== '2' || input.tab !== '3'"

is TRUE when the tab isn't 2 or isn't 3, which is always. By changing it to:

condition = "input.tab !== '2' & input.tab !== '3'"

changing the tab to 2 or 3 is enough to make the statment FALSE and hide the tab
