The two instantiation options addContentToHeader and addContentToFooter can be used to add custom content at the beginning and end when exporting png、svg、pdf, The default value is null, which means no configuration. A function can be passed and can return null, which means no content will be added. If you want to add content, you need to return the following structure:
{
+ el,// Custom DOM node to be added, styles can be inline
+ cssText,// Optional, if the style does not want to be inlined, you can pass this value as a CSS string
+ height: 50// The height of the returned DOM node must be passed
+}
+A simple example:
+new MindMap({
+ addContentToFooter: () => {
+ const el = document.createElement('div')
+ el.className = 'footer'
+ el.innerHTML = 'From: simple-mind-map'
