Collapse sidebar (Table of Contents, left side) section

Question

How can I add the 'Collapse sidebar' button to my own Docusaurus website, as shown below?

Answer 1

Inside your docusaurus.config.js, you need to add the parameter hideableSidebar: true, in the themeConfig category.

EXAMPLE

(module.exports = { // start of the module.export declaration
[…]

    themeConfig: {
        hideableSidebar: true,
        […] 
    }

[…] 
}); // end of the module-export declaration
