Introduction

When creating a dashboard with R Quarto, using the bslib library to create value boxes can be a great way to display important information in a visually appealing way. However, by default, the Expand button is displayed in the bottom right corner of the value box, which may not be desirable in all cases. 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 for creating Bootstrap components, including value boxes. It provides a simple and intuitive way to create value boxes with various styles and customization options. However, as with any library, there may be cases where you need to customize the behavior of the value box, such as removing the Expand button.

Default Value Box Behavior

By default, the value box created with the bslib library displays an Expand button in the bottom right corner. This button allows users to expand the value box to display more information. While this can be useful in some cases, it may not be desirable in all cases, especially when you want to display a simple value without any additional information.

Removing the Expand Button

To remove the Expand button from the value box, you can use the expand argument in the value_box function provided by the bslib library. The expand argument is a logical value that determines whether the value box should display the Expand button. By setting expand to FALSE, you can remove the Expand button from the value box.

Here is an example of how to create a value box without the Expand button:

library(bslib)

value_box(
"Value Box without Expand Button",
value = "This is a value box without an Expand button.",
expand = FALSE
)

In this example, we create a value box with the title "Value Box without Expand Button" and the value "This is a value box without an Expand button." We set the expand argument to FALSE to remove the Expand button from the value box.

Customizing the Value Box

In addition to removing the Expand button, you can also customize the value box to suit your needs. For example, you can change the background color, text color, and font size of the value box. You can also add additional information, such as a subtitle or a footer, to the value box.

Here is an example of how to customize the value box:

library(bslib)

value_box(
"Customized Value Box",
value = "This is a customized value box.",
subtitle = "This is a subtitle.",
footer = "This is a footer.",
bg_color = "lightblue",
text_color = "darkblue",
font_size = 18
)

In this example, we create a customized value box with the title "Customized Value Box" and the value "This is a customized value box." We add a subtitle and a footer to the value box and customize the background color, text color, and font size of the value box.
