Lasagna

Add layers, toggle them using tags easily

Getting Started

Here is a short snippet of the package in action:

#import "@preview/lasagna:0.1.0": *
#let layer = view-layer(tags: ("shown"))

This is always shown
#layer("hidden")[
    This is hidden
    #layer("shown")[
        But this is shown
    ]
]
#layer(("shown", "another-tag"))[
    You can also assign multiple tags, as long as 1 tag matches it will be shown
]

Usage

Here are some examples on how this package can be utilized.
