Improving Conditional Panels in Shiny: A Solution to Shared Input Names

Based on the provided code, I will provide a rewritten version that addresses the issue with multiple conditional panels having the same input name.

Code Rewrite

# Define a Shiny module to handle conditional panels
shinyModule(
  "ConditionalPanel",
  server = function(input, output) {
    # Initialize variables
    ksmin <- reactiveValues(ksmin = NA)
    
    # Function to get norm data
    getNormData <- function(transcrit_id, protein_val) {
      # Implement logic to calculate norm data
      # ...
    }
    
    # Function to fit test RNA
    fitTestRNA <- function(dpa, norm_data_mrna) {
      # Implement logic to fit test RNA
      # ...
    }
    
    # Function to solve for sol K
    solveSolK <- function(dpa, protein_vec, ks) {
      # Implement logic to solve for sol K
      # ...
    }
    
    # Define output for each panel
    output$panel1 = renderUI({
      req(input$fit_mrna != "")
      
      # Use a unique input name for each panel
      ksmin(value = 10)
      
      # Render UI elements
      textInput("par1", "Input 1")
      conditionalPanel(
        input$condition_1 == "value",
        textInput("par2", "Input 2")
      )
    })
    
    output$panel2 = renderUI({
      req(input$fit_mrna != "")
      
      # Use a unique input name for each panel
      ksmin(value = 10)
      
      # Render UI elements
      textInput("par3", "Input 3")
    })
  }
)

# Define the main app
ui <- fluidPage(
  conditionalPanel("input.condition_1 == 'value'", 
                   panelUI({
                     textInput("par1", "Input 1")
                     conditionalPanel("input.par2 == 'value'", 
                                      panelUI({
                                        textInput("par4", "Input 4")
                                      }))
                  }),
                   panelUI({
                     textInput("par3", "Input 3")
                   })
                  )
  )
)

# Run the app
app <- shinyApp(ui = ui, server = function(input, output) {
  # Run the module for each panel
  run_panel1 <- reactiveValues(module = ConditionalPanel())
  
  run_panel2 <- reactiveValues(module = ConditionalPanel())
  
  # Render output for each panel
  output$panel1 = renderUI(run_panel1.module)
  output$panel2 = renderUI(run_panel2.module)
})

# Run the app
shinyApp(app)

Explanation

I defined a Shiny module (ConditionalPanel) that handles conditional panels. The module uses reactive values to store the input data and functions to calculate norm data, fit test RNA, and solve for sol K.
In the main app, I used fluid pages with conditional panels. Each panel has its own unique input name.
I ran the Shiny module for each panel using reactiveValues and rendered the output using renderUI.
This approach allows you to reuse the same module for multiple conditional panels with different input names.

This rewritten version should address the issue with multiple conditional panels having the same input name.
