+	```julia
+	details(summary::AbstractString, contents; open::Bool=false)

+
+	Create a collapsable details disclosure element (`<details>`).
+
+	Useful for initially hiding content that may be important yet overly verbose or exposing advanced variables that may not always need displayed.
+
+	# Arguments
+
+	- `summary::AbstractString`: the always visible summary of the details element.
+	- `contents::Any`: the item(s) to nest within the details element.
+
+	# Keyword arguments
+
+	- `open::Bool=false`: whether the details element is initially open.
+
+	# Examples
+
+	```julia
+	details("My summary", "Some contents")
+	```
+
+	```julia
+	details(
+		"My summary",
+		[
+			"My first item",
+			(@bind my_var Slider(1:10)),
+			md"How are you feeling? \$(@bind feeling Slider(1:10))",
+		],
+		open=true,
+	)
+	```
+
+	!!! warning "Beware @bind in collection declaration"
+		You may want to `@bind` several variables within the `contents` argument by declaring a collection of `@bind` expressions. **Wrap each `@bind` expression in parenthesis** or interpolate them in `md` strings like the example above to prevent macro expansion from modifying how your collection declaration is interpreted.
+
+	```julia
+	# This example will cause an error
+	details(
+		"My summary",
+		[
+			"My first item",
+			@bind my_var Slider(1:10),
+		]
+	)
