I am quite new with css styling and I have the following app:
library(shiny)
ui <- fluidPage(
tags$head(
tags$style(
type = "text/css",
"#txtXDiv label, #txtYDiv label {
display: table-cell;
text-align: left;
vertical-align: middle;
width:130px
}
#txtXDiv .form-group, #txtYDiv .form-group {
display: table-row;
}
/*#txtXDiv, #txtYDiv {
display:inline-block
}*/
"
)
)
,tags$div(
id = "txtXDiv",
textInput(inputId = "txtX", label = "Porcentaje X:"),
p("%")
)
,tags$div(
id = "txtYDiv",
textInput(inputId = "txtY", label = "100 - Porcentaje X:"),
p("%")
)
)
server <- function(input, output) {}
shinyApp(ui = ui, server = server)
It looks in this way:
What I want is:
To reduce the width of the input field
To put the "%" character together at the right of the input field
I mean, something like that
Any suggestion?

There are a few solutions here and here but none of them works on Shiny 1.3.2.
This is what I attempted so far
library(shiny)
server <- shinyServer(function(input, output) { NULL })
ui <- shinyUI(
pageWithSidebar(
headerPanel("side-by-side"),
sidebarPanel(
fluidRow(
tags$head(
tags$style(type="text/css", "label.control-label, .selectize-control.single{ display: table-cell; text-align: center; vertical-align: middle; } .form-group { display: table-row;}")
),
column(2),
column(4,
sliderInput("slider", label = h5("slider") ,value = 500,min = 0, max =1000,ticks = F)
)
)),
mainPanel(
fluidRow(
h3("bla bla")
))
)
)
shinyApp(ui=ui,server=server)
Is there a way to make the slider wider?
There’s a lot of different ways to do positioning with CSS. My choice here would be to use flexbox, as annotated below. Note the use of a
.label-left container to scope the positioning changes.
library(shiny)
ui <- fluidPage(
tags$style(HTML(
"
.label-left .form-group {
display: flex; /* Use flexbox for positioning children */
flex-direction: row; /* Place children on a row (default) */
width: 100%; /* Set width for container */
max-width: 400px;
}
.label-left label {
margin-right: 2rem; /* Add spacing between label and slider */
align-self: center; /* Vertical align in center of row */
text-align: right;
flex-basis: 100px; /* Target width for label */
}
.label-left .irs {
flex-basis: 300px; /* Target width for slider */
}
"
)),
div(class = "label-left",
sliderInput("slider_1", "First slider", 0, 10, 5),
sliderInput("slider_2", "Second slider", 0, 10, 5)
)
)
server <- function(input, output, session) {}
shinyApp(ui, server)
I'm wondering whether these is any option to include math mode in tooltip title using bsTooltip() from shinyBS package.
Small example:
rm(list = ls())
library(shiny)
library(shinyBS)
ui <- basicPage(
headerPanel("Tooltip test"),
bsTooltip(id = "Equation", title = "\\(\\bar{X} = \\frac{1}{n}\\sum_{p = 1}^{n}X_p\\)", placement = "bottom", trigger = "hover", options = NULL),
mainPanel(
p("some text", htmlOutput("Equation", inline = TRUE))
)
)
server <- shinyServer(function(input, output,session) {
output$Equation <- renderUI({HTML("<font color='blue'><u>something which needs equation</u></font>")})
})
shinyApp(ui = ui, server = server)
The result (math mode) is not satisfactory:
No way with 'shinyBS'.
Here is a way using the qTip2 JavaScript library.
In order to use it, you have to download the files jquery.qtip.min.css and jquery.qtip.min.js, and put these two files in the www subfolder of the Shiny app.
library(shiny)
js <- "
$(document).ready(function() {
$('#Equation').qtip({
overwrite: true,
content: {
text: $('#tooltip')
},
position: {
my: 'top left',
at: 'bottom right'
},
show: {
ready: false
},
hide: {
event: 'unfocus'
},
style: {
classes: 'qtip-youtube qtip-rounded'
},
events: {
blur: function(event, api) {
api.elements.tooltip.hide();
}
}
});
});
"
library(shiny)
ui <- basicPage(
tags$head(
tags$link(rel = "stylesheet", href = "jquery.qtip.min.css"),
tags$script(src = "jquery.qtip.min.js"),
tags$script(HTML(js)),
),
withMathJax(),
headerPanel("Tooltip test"),
mainPanel(
p("some text", htmlOutput("Equation", inline = TRUE)),
div(
id = "tooltip", style = "display: none;",
HTML("$$\\int_0^1 f(x) dx = \\pi$$")
)
)
)
server <- shinyServer(function(input, output,session) {
output$Equation <-
renderUI({HTML("<font color='blue'><u>something which needs equation</u></font>")})
})
shinyApp(ui = ui, server = server)
Just to add another option, we could create our own tooltip class following the example from W3 here. Then we can use {shiny}'s withMathJax() function to render the tooltip as formula.
I usually use custom tooltips in cases where I only have a few tooltips that I want to customize. It has the advantage that it comes with no additional dependencies. The major drawbacks of this custom tooltip are that (1) it is displayed as child element and not in a separate container on the top layer like tooltips generated with javascript and that (2) you have to create css classes for each arrow direction. So if you have many tooltips pointing in different directions an additional javascript library like qTip2 should be definitely worth the dependency.
library(shiny)
ui <- fluidPage(
tags$head(
tags$style(HTML(
# tooltip implementation from:
# https://www.w3schools.com/css/tryit.asp?filename=trycss_tooltip_arrow_top
# just added a `t` to make classes unique
".ttooltip {
position: relative;
display: inline-block;
border-bottom: 1px dotted black;
}
.ttooltip .ttooltiptext {
visibility: hidden;
width: 120px;
background-color: black;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 5px 0;
position: absolute;
z-index: 1;
top: 150%;
left: 50%;
margin-left: -60px;
}
.ttooltip .ttooltiptext::after {
content: '';
position: absolute;
bottom: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: transparent transparent black transparent;
}
.ttooltip:hover .ttooltiptext {
visibility: visible;
}")
)
),
headerPanel("Tooltip test"),
mainPanel(
p("some text", htmlOutput("Equation", inline = TRUE)),
))
server <- shinyServer(function(input, output,session) {
output$Equation <- renderUI({
span(class = "ttooltip",
style = "color: blue",
"something which needs equation",
span(class = "ttooltiptext",
withMathJax("$$\\bar{X} = \\frac{1}{n}\\sum_{p = 1}$$"))
)
})
})

I have tried to set the distance between two widgets, offset= 0 in column() doesn't work. Can anyone please help me on this, I have stuck here for many hours! Thank you!
library(shiny)
ui <- fluidPage(
column(4,
fluidRow(
tags$head(
tags$style(type="text/css", "label{ display: table-cell; text-align: center; vertical-align: middle; } .form-group { display: table-row;}")
),
textInput(inputId = "txtInp", label = "Label = ")
)),
column(4,
fluidRow(
tags$head(
tags$style(type="text/css", "label{ display: table-cell; text-align: center; vertical-align: middle; } .form-group { display: table-row;}")
),
numericInput(inputId = "numInp", label = "X", value = 0)
))
)
server <- function(input, output){}
shinyApp(ui, server)
I'm struggling to find out how to target 1 of the two dropdowns specifically with css styling code.
I can style the dropdowns in general, but not individually
I have tried to target it in the following ways, but none work.
#MyDropDown1 .sw-show.sw-dropdown-content {
#sw-content-MyDropDown1 .sw-show.sw-dropdown-content {
.dropdown-content-MyDropDown1 {
#dropdown-content-MyDropDown1 {
#dropdown-menu-MyDropDown1 {
How to find the right syntax to target the 1st dropdown?
here is the app:
library(shiny)
library(shinyWidgets)
ui <- fluidPage(
tags$head(tags$style(HTML('
.sw-show.sw-dropdown-content {
display: block;
left: 200px;
top: 100px;
height: 300px;
width:
} '))),
dropdown(inputId = "MyDropDown1",
tags$h3("List of Input")),
dropdown(inputId = "MyDropDown2",
tags$h3("List of Input"))
)
server <- function(input, output, session){
}
shinyApp(ui = ui, server = server)
Maybe this is a way to go. But unfortunately because of the margin I end up with 2 boxes...
But at least the css style apply only on the first dropdown
library(shiny)
library(shinyWidgets)
ui <- fluidPage(
tags$head(tags$style(HTML('
.test {
display: block;
background-color:red;
left: 200px;
top: 100px;
height: 300px;
width:
} '))),
dropdown(inputId = "MyDropDown1",
tags$h3("List of Input"), class = "test"),
dropdown(inputId = "MyDropDown2",
tags$h3("List of Input"))
)
server <- function(input, output, session){
}
shinyApp(ui = ui, server = server)
I would like some inputs to have their label inline with the input box, and others to exhibit the standard Shiny standard behaviour. Consider the answer (and minimal example) given by SBista here: How to put a box and its label in the same row? (shiny package)
library(shiny)
ui <- fluidPage(
fluidRow(
tags$head(
tags$style(type="text/css", "label{ display: table-cell; text-align: center; vertical-align: middle; }
.form-group { display: table-row;}")
),
textInput(inputId = "txtInp", label = "Label:"),
textInput(inputId = "txtInp2", label = "A_longer_label:"),
numericInput(inputId = "numInp", label = "Third_label:", value = 0)
)
)
server <- function(input, output){}
shinyApp(ui, server)
This gives the very neat output like so:
Here the input boxes are neatly aligned. If I only want some of the labels to exhibit this behaviour (and others to do the normal Shiny thing), I can create the id "inline" and add it to divs around the labels in question, like so:
library(shiny)
ui <- fluidPage(
fluidRow(
tags$head(
tags$style(type="text/css", "#inline label{ display: table-cell; text-align: left; vertical-align: middle; }
#inline .form-group { display: table-row;}")
),
tags$div(id = "inline", textInput(inputId = "txtInp", label = "Label:")),
tags$div(id = "inline", textInput(inputId = "txtInp2", label = "Label2_not_inline:")),
numericInput(inputId = "numInp", label = "Third_label:", value = 0)
)
)
server <- function(input, output){}
shinyApp(ui, server)
Now the third label behaves as expected, but the first two labels are not neatly aligned. I guess this is because an id can only be used once. How can a class be used to achieve the desired result for multiple inputs?
To achieve what you want you could modify the css as follows:
tags$style(type="text/css", ".inline label{ display: table-cell; text-align: left; vertical-align: middle; }
.inline .form-group{display: table-row;}")
The code would look something like this:
library(shiny)
ui <- fluidPage(
fluidRow(
tags$head(
tags$style(type="text/css", ".inline label{ display: table-cell; text-align: left; vertical-align: middle; }
.inline .form-group{display: table-row;}")
),
tags$div(class = "inline", textInput(inputId = "txtInp", label = "Label:"),
textInput(inputId = "txtInp2", label = "Label2:")),
numericInput(inputId = "numInp", label = "Third_label:", value = 0)
)
)
server <- function(input, output){}
shinyApp(ui, server)
With this code you will get the labels which looks a lot cleaner, something like this:
Hope it helps!
