Set Default Chapter-Toggle I experienced that it annoys me alot that you always need to Open the Drop-Down from each Chapter. Which looks like this: Enter Custom Code So i found a Way on how to set a Default to always toggle those Chapter open. Basicly you only need to open the Bookstack "Settings-Page" from your Wiki and then open the "Customization" Tab, scroll to the Bottom of the Page and insert the following Code into the "Custom Code Section": Your Result would then look like this :)
