Shiny splitLayout and selectInput issue
<p>When I combine the splitLayout and selectInput in R Shiny, there is something wrong.</p>

<p>The dropdown list of choices cannot be displayed properly. </p>

<p>How can we address this issue.</p>

<p>Please check the reproducible code.</p>

<pre><code>library(shiny)

server &lt;- function(input, session, output) {

  output$select_1 = renderUI({
    selectInput("select_input","select", choices = LETTERS)
  })



}

ui &lt;- fluidPage(
  splitLayout(
    uiOutput("select_1")
  )
)

shinyApp(ui = ui, server = server)
</code></pre>

<p>I have 8 selectInputs that I want to place evenly side by side in one row. </p>

<p>Using fluidrow is not OK because the column width can only be integers. </p>

<p>I wonder if there is any alternative way to do this.</p>
