@makiz1999 Thanks. Could you point to where this is? Screenshots are not helpful to search/find resources.

Yeah, here is the link: https://quarto.org/docs/dashboards/data-display.html#dynamic-titles

It is from https://quarto.org/docs/dashboards/data-display.html#dynamic-titles

I'll look into this

@makiz1999 are you using this in format: dashboard ?

This will only work in this format, and it works for me it seems

---
title: Test
format: dashboard
keep-md: true
---

```{r}
library(leaflet)

lat <- 48
long <- 350

cat("title=", "World Map at", lat, long)

leaflet() |> addTiles() |> 
  setView(long, lat, zoom = 2)
```

The card correctly get the title

This is specific feature of Dashboard format to set a title to a Card output

Hi, thank you. I missed one element in my code.

Do you know by chance if it's possible to dynamically change the title using a reactive component? In other words, the title would reflect user input from the dropdown selector.

Screenshot below shows the idea

I don't think this is possible because the feature is used by quarto render and it is only rendered once.

any shiny reactive can't be used in there.

Maybe there is a way to use some raw HTML that shiny understand, but this is not easy.

So unfortunately with this syntax, I don't think this can be done. I need to think about how this could be done in a dashboard. 🤔
