How do I use Interact.jl to present a list of checkboxes with some of the boxes already checked off? Tried following the documentation and couldn’t figure out how to set specific checkboxes to true (i.e. checked off).

What I have currently, is this:

The boxes are empty by default. What I would like to have happen is for a few boxes to already be checked off when they are first shown like this:

The code I have been using is:

```julia
using Interact
options = Observable(["a", "b", "c"])
wdg = checkboxes(options)
wdg

```

Thanks!

Issue opened here as it is still unclear how to achieve this: [https://github.com/JuliaGizmos/Interact.jl/issues/386](https://github.com/JuliaGizmos/Interact.jl/issues/386)

I figured it out! Thanks to @piever , here is a solution that works:

```julia
options = ["a", "b", "c"]
value = ["a", "c"]
checkboxes(options, value = value)

```
