General ⇒ Missing } inserted / Nesting commands

[ecastro]

Hi,

I'm trying to create some checklists with Latex using a template that I've found here: https://github.com/mavcunha/checklists/ ... eamble.inc

I want to do some special things, such as getting some items in the checklist to have a colored background. So I tried to do something like:

Code: Select all

Code, edit and compile here:

\begin{checklist}{Cockpit}
    \colorbox{blue!10}{
      \item{Gear switch}              {VERIFY DOWN}
      \item{Magneto/Starter}          {VERIFY OFF}
      \item{Avionics Switch}          {VERIFY OFF}
      \item{Master Switch}            {SET ON}
      \item{Fuel gauges, quantity}    {CHECK}
    }
    \item{Pitot heat}               {SET ON}
    \item{Interior/Exterior lights} {SET ON}
    \item{Interior lights}          {CHECK}
    \item{Exterior lights}          {CHECK}
  \end{checklist}

But I'm getting the Missing } inserted.

I have already invested some hours and I cannot fully understand the issue, let alone how to fix it!

Any help?!

Hi,

welcome to the forum!

You cannot have \item inside a \colorbox. If you take the box out, it works:

Code: Select all

Perhaps use color within \item.

Thanks Stefan for the quick reply. Maybe I should have stated the end result that I'm looking for rather than the issue I'm having.

So I want to achieve something like this:

2023-04-21 10_53_26-Missing } inserted _ Nesting commands — Mozilla Firefox.png (26.31 KiB) Viewed 1640 times

I tried doing it inside item command but was not able to achieve this result, then I tried doing it outside and I get this error.

Could you point me in the right direction on how to achieve something like this?

You could use the commands of the colortbl package to color the table rows. The xcolor package manual tells you how to load it.
