.tabset-dropdown's menu right icon doesn't render properly with self_contained: false

[cpsievert]

For a minimal example, put this minimal example in a rmarkdown website

[yihui]

I also noticed this problem two weeks ago, but didn't look into it. This is another reason why I wanted to drop this feature.

[cpsievert]

This looks to be related to self_contained. Here's a minimal example:

---
title: "tabset dropdown"
output:
  html_document:
    self_contained: false
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

# R Markdown {.tabset .tabset-dropdown}

## Tab A

This is an R Markdown document. 

## Tab B

When you click the **Knit** button a document will be generated.

## Tab C

Here is a summary table.

```{r cars}
summary(cars)
```

## Tab D

Here is a plot:

```{r pressure, echo=FALSE}
plot(pressure)
```

# Here is another section {.tabset}

## Tab A

This is content in a standard tabset.

## Tab B

This is more content in a standard tabset.

any idea if it was a problem from the very beginning when https://github.com/rstudio/rmarkdown/pull/1405 got implemented or it appears later on, for example when migrating to bs4?

It has always been an issue

[alenastern]

hello! I was wondering if this issue has been resolved, I am currently encountering this issue when I add a navbar to my R Markdown file knitted to html (the tabset-dropdown works as expected when knitting without _site.yml)

I've pasted my site.yml file below:

name: Recovery Funds Dashboard
navbar:
  title: Recovery Funds Dashboard
  left:
  - text: Home
    href: index.html
  - text: FAQ
    href: faq.html
  - text: Glossary
    href: glossary.html
output:
  html_document:
    output_dir: '.'
    css: !expr here::here("www", "web_report_trust.css")
    self_contained: TRUE
output_dir: '.'

index.html is the page that has the issue (see screenshot below). All of the component markdown files (including index.Rmd) set self_contained: TRUE

Thanks so much for your help!

Similar to @alenastern I am also still having this issue...does a solution exist?

[cderv]

Thanks for pinging again @michaelofrancis

I have pushed a fix that it simpler than unmerged #2054

It should work as expected

[michaelofrancis]

It works! Thank you.

[alenastern]

I revisited this thread in the hopes of incorporating the fix but I'm still having the same issue posted in my original comment above. @michaelofrancis @cderv - are there any package/software updates I need to make in order to implement the fix?

@alenastern you are using an old R Markdown version - The fix is in rmarkdown 2.17

You need to update.

[alenastern]

@cderv thanks so much!
