# Putting tikzpictures in section headers

Can you put tikzpictures into a section header?

For example, I'm trying to put the tikzpicture defined in the top rated answer of

LaTeX "under construction", "in work" or "work in progress" symbols

into my section header. The picture works fine in the main document, but as soon as I put it into a section header, I get a bunch of mysterious errors.

Below I've included some sample code that compiles. However if you replace "\section{test}" with "\section{test \WIP{0.2}}", then the desired "work in progress" symbol appears in the section header, but the compiler spits out tons of error messages I can't parse. Moreover, the symbol does not appear properly in "tableofcontents".

Are there any workarounds for this?

• Try "robustifying" \WIP with \usepackage{etoolbox}\robustify{\WIP}? Aug 12, 2020 at 2:39
• tex.stackexchange.com/a/463237/197451 -- Anything inside sectioning commands must be robust or protected using \protect, so you need to change you \newcommand to \DeclareRobustCommand Aug 12, 2020 at 3:43
• @imnothere Thank you! Robustify worked! Aug 12, 2020 at 5:12
• @jsbibra Hmm \DeclareRobustCommand didn't work. Still getting errors. Though, imnothere's suggestion using \robustify did work for some reason. Aug 12, 2020 at 5:12
• And what about using titlesec package? Aug 12, 2020 at 12:45
