Introduction

When creating a dashboard using R Quarto and the bslib library, you may encounter a situation where the default value box displays an expand button in the bottom right corner. This can be distracting and may not be suitable for your dashboard's design. In this article, we will explore how to remove the expand button from the value box in a Quarto dashboard.

Understanding the bslib Library

The bslib library is a popular R package used for creating beautiful and interactive dashboards. It provides a wide range of features, including value boxes, which are useful for displaying key metrics or statistics. However, as mentioned earlier, the default value box displays an expand button, which may not be desirable in all cases.

Removing the Expand Button

To remove the expand button from the value box, you can use the bslib library's value_box function and set the expand argument to FALSE. Here's an example code snippet:

library(bslib)

value_box(
"Key Metric",
"This is a key metric",
expand = FALSE
)

In this example, we create a value box with the title "Key Metric" and the text "This is a key metric". We set the expand argument to FALSE to remove the expand button.

Customizing the Value Box

In addition to removing the expand button, you can also customize the value box to suit your dashboard's design. For example, you can change the background color, text color, and font size. Here's an example code snippet:

library(bslib)


value_box(
"Key Metric",
"This is a key metric",
expand = FALSE,
bg = "lightblue",
fg = "black",
font_size = 16
)

In this example, we create a customized value box with a light blue background, black text, and a font size of 16.

Using Quarto to Create a Dashboard

Quarto is a powerful tool for creating interactive dashboards. It allows you to write your code in R Markdown and then render it into a beautiful and interactive dashboard. To create a dashboard using Quarto, you can use the following code:

---
title: "My Dashboard"
output:
  bslib::bs_theme: default
  bslib::bs_value_box: default
---


value_box(
"Key Metric",
"This is a key metric",
expand = FALSE
)

In this example, we create a Quarto document with a title and an output section that specifies the theme and value box settings. We then create a value box without the expand button using the value_box function.
