Just a warning: This plugin causes tabs created by another plugin to be treated as anchors, causing the page to jump whenever a tab is clicked. Unfortunately, this pushes the tabs just off the top of the screen, and with vertical tabs hides the top of the text contained in the tab.
TRhis makes the tabs pretty much unusable, so you have to choose which plugin is most important and dump the other.
Such a simple yet INGENIOUS little plugin that elegantly solves a bugger of an issue with Gutenberg WordPress... inserting "Anchors" (i.e. Page Jumps) into pages. As someone who can edit HTML code quite well, I find it awkward how WordPress makes it to add "anchors" to any place in a document OTHER THAN Headers (Gutenberg has this built in, but JUST for headers). Trying to add the HTML code id="xyz" to anywhere else (text, pictures, etc) forces you to convert the block to pure HTML, thereby losing the block editing structure for all else related to that particular block. So now you have to work with BOTH Block and HTML content on a single page. There is no way to just add the HTML "id code" and keep the existing Gutenberg Block editing structure for all other aspects of the paragraph or picture. Trust me, if I wanted to work in HTML, I would. But there are reasons why I use WordPress and this one caveat of forcing mixed editing styles is just dysfunctional.
Enter Gutenberg Anchor BLock! Simply add it to your page, just as you would any other block, just above where you want an anchor point, enter a unique name for the anchor, and voila... you're DONE!
A genius of an idea for which the developer, Jean-Baptiste Audras, should get royalties when it becomes a built-in of the next Gutenberg update.
See, it truly IS the little things in life that make you the happiest!
